Building a Global Space Network

This is a project that I am involved in and although it is not a personal project at this time, it is none the less a project that I have instigated. It is a project that is being handled under my Company PlusComms – I am a major shareholder. Press Release below:

Date: Thursday 22nd September 2011

Sydney, Australia

PlusComms Pty Limited based in Sydney, Australia has announced that it is building a Global Deep Space Network (DSN) subject to financing. The project involves 3 x 30m dishes in key locations around the world. The Project, called MissionTrax could be operational by first quarter 2014.

The driver for the project has been to locate large dishes with a 30 year or more lifetime and bring them back to full service. Not only is this a very environmentally friendly approach, but it also has the added benefit of costing 1/10th the price of building a new service with the same specifications. The first dish is located in California on the east coast of the USA. The site will be purchased and refurbished to operational standards, but it will be no longer used as a satellite “Earth station”. It will soon be part of a global network able to continuously track almost anything around the equatorial plane + or – 40 degrees. Although the coverage has yet to be tested at a range of frequencies, it is expected that missions as far away as Mars will have continuous coverage from Earth (excluding the rotation of Mars). The distance to Mars at the at the furthest point from Earth is 401 million km / 250 million miles – that is just under 3 Astronomical Units – or just under 3 times the distance from the earth to the sun. The three sites need to be on longitude that is 120 degrees from each other.

CTO of PlusComms, Robert Brand said “The extent of the coverage of course depends on the frequency being used and the power of the spacecraft. It is expected that communications with spacecraft near outer planets will also be part of the GSN’s capabilities but further testing will be done to confirm the overall performance of each dish and the complete network”.

“Modern satellite technology now allows dishes to be small and able to be placed in city locations. These older 30m dishes were built big to gather the weak signals and were located in “radio signal” quiet areas because the signals were hard to process. This makes these original workhorses redundant for tracking communications satellites, but perfect for building a DSN. Each GSN site will provide overlapping coverage of the previous site at a distance around 30,000 to 35,000km from the Earth’s surface (the blue circle in the attached diagram. These dishes were also built to a high tolerance and have specifications to over 15GHz. They are also Beam Wave Guide (BWG) dishes and thus the signal is beamed in a big tube right to the control room. This allows us to build a railway track to quickly disconnect and shunt in new equipment for different bands and capabilities. It is expected that it will take 45mins to connect and align a unit and 15 minutes to disconnect, allowing a one hour booking for a quick link with a spacecraft or rover / experiment on Mars or the Moon. The site will also provide full TT&C capability to fire engines and control satellites

In addition to the GSN capability, the US site will also be equipped as a large hosting centre for servers and other systems, with the ability to have individual partitions for companies. These sites were built to withstand a nearby blast from a nuclear bomb. With massive concrete walls the US site has amazing security and the ability to act as redundant site for most applications and secure the continued data operations of companies. The site already has fiber connectivity and plenty of room for more dishes. It is expected that this site will have multi-tenant uses.

“We would also like to return something to the global community and stimulate students by allowing automated access for basic Radio Telescope work when not booked for space tracking. We will employ automated systems via the Internet to explore the sky. The large dish may also be used for special events by other not for profit groups” Brand said. “The service will be headquartered in Sydney Australia. With the number of private space missions predicted to climb rapidly and a focus on the Moon and Mars, we expect a real growth in business over the next few years.”

UpLift-1 APRS Tracking (Archives)

APRS – The Best Balloon Tracking Solution

There are many ways to track balloons. There is the Radiosonde, Mobile Phone (3G), HAM radio APRS and many more. Since I both work in Radio Telecommunications and I am a HAM radio operator (VK2URB), then it is an easy choice. The amateur radio APRS system is ideal.

So what are these systems in brief:

Radiosonde: Wikipedia says: “A radiosonde (Sonde is French for probe) is a unit for use in weather balloons that measures various atmospheric parameters and transmits them to a fixed receiver. Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz and both types may be adjusted slightly higher or lower as required.” This sounds more like a license is required and special Radiosonde equipment is needed.

GPS enabled mobile / cellular smart phones: We all know what these are, but do they work?. Firstly you had better hope that your payload drops in a coverage area. These work by sending an SMS to the phone on the balloon and it then relays its position back to you via another SMS. Mobile telephone coverage in rural areas might not allow you to get a fix on the balloon as it parachutes back to earth. There is also the issue of the GPS receiver. Most do not work at heights over 60,000 feet (20kms) and thus you do not know how high it got or when it is descending. Many people on a tight budget try to use cellular phones and many have great success.

UHF Tracking: Similar to Radiosonde, yet it operates on a low power UHF channel, often used for garage door openers, etc. It transmits the co-ordinates for the GPS location and must be tracked by radios especially set up to receive the transmissions. The data is often ported to the internet for display on a web page. Handheld yagi antennas are directional and look like UHF yagi TV antennas seen on rooftops and are used to track the payload when it is on the ground or in the air.

APRS_TestTrackHAM Radio APRS:This is the choice that I feel best suits the situation and given that I already have a HAM license, then I do not have to ask others to help. What is APRS?: Wikipedia says: Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time tactical digital communications of information of immediate value in the local area. In addition, all such data is ingested into the APRS Internet system (APRS-IS) and distributed globally for ubiquitous and immediate access. Along with messages, alerts, announcements and bulletins, the most visible aspect of APRS is its map display. Anyone may place any object or information on his or her map, and it is distributed to all maps of all users in the local RF network or monitoring the area via the Internet. Any station, radio or object that has an attached GPS is automatically tracked. Other prominent map features are weather stations, alerts and objects and other map-related amateur radio volunteer activities including Search and Rescue and signal direction finding. APRS has been developed since the late 1980s by Bob Bruninga, call sign WB4APR, currently a senior research engineer at the United States Naval Academy. He still maintains the main APRS website. The acronym “APRS” was derived from his callsign.

Note the unusual off-white unit connected with wires in the top picture – it is the special high altitude GPS receiver. It will work up to very high altitudes but sacrifices some accuracy.

The picture above is the APRS Test Track around a street block on a hill near my home. Not precise, but very close. I was shaking the thing as I walked to make it hard for the system. I walked counter / anti clockwise from near the top without shaking and then where it goes a funny in the last quarter of the short walk I was really shaking it wildly. The unit reports on many details. These are:

VK2URB-11 is the balloon call sign

2011-09-10 02:59:41z is the date and time in GMT/Zulu

7 km/h was my walking speed

248 degrees was my bearing

alt 80m was my height above sea level

05.8v was the tracker battery voltage

20C was the temperature – about 70F

The other data is pressure, HHMMSS, and number of GPS satellites, the digipeater used (if used) and the iGate used.

Agilant systems APRS transmitter for balloonsPluses and Minuses

APRS is could always be better and there are not too many iGates (APRS gateways into the Internet) in rural areas, so you must check first. In fact I have chosen to have my balloon drop near Parkes for that very reason. There is an iGate in Parkes and the Digipeater (digital repeater) at nearby Mt Canobolas will also pick up the transmissions from my balloon. I have also chosen an area for good 3Gcellular coverage to assist with tracking and maps. Just to be sure, I will have a digipeater in my car so that if I am not too far away the position will be relayed by my car to the Internet for easy tracking. The unit I have chosen is specifically bought for ballooning. It is from Argent Data in the US. The unit weighs only 160 grams (5.6 ounces). It transmits half a watt (500mW). It is pictured top right and is a pre-release model.

The next issue is finding it when on the ground. Radiosonde and APRS are well suited to this task, but the APRS has a few tricks up it’s sleeve. Fist it might be able to radio its GPS co-ordinates to the Internet tracking system. As I get close with the digipeater, it will also do that job if no other iGates are in range. Secondly it may be picked up directly by my handheld radio, nice, but since it only transmits for 1-2 seconds, it will be hard to get a fix on the unit. Finally I can decode the data with my iPhone and simple read its exact co-ordinates. Nice! That is the directly decoded packets on the right. I did the test inside my house so the GPS coordinates will not be seen.

On the minus side, there is the need for an amateur radio license and access to the expense and homemade equipment that is either out of reach of some people financially or technically.

I also replaced the long general purpose whip antenna that you can see on the top image with a highly tuned light weight dipole. It is made of hollow brass and this also makes it easy to slide some stiff wire inside the antenna for tuning. The wire was then soldered in place to get the tuning very precise. This maximizes the antenna’s radiation ability at the precise frequency of the APRS system. We are using VHF at 145.175MHz. The pictures below show the modification. The work was done by my good friend Bruce who I have worked with on and off for over 40 years. He is also an amateur radio operator (VK2ZZM) and I am very appreciative of his advice and help on the APRS side of this project.

APRS Transmitter dipole antenna

The white Styrofoam under the unit is the lid of the UpLift-1 capsule. The antenna is mounted on a small printed circuit board, The copper wire is used to add strength to the copper on the board in case of mechanical failure that may make the copper peel from the board.

APRS Tracker with dipole antenna - back

The rear side above showing the bolts that pass through to the battery mounts on the tracker unit. A small amount of “locktight” was placed on the nuts to make sure that mechanical vibration did not make them fall off.

Spectrum / Network Analyser tuning the APRS tracker Dipole antenna

This is a state of the art network analyzer. It is measuring Return Loss. Send a signal to the antenna and what is not radiated comes back. The dip means that it is tuned to the frequency and radiating well. It is right on the tracker frequency. The Marker frequency. It is perfectly tuned and radiating the signal – not much is being reflected back into the cable. It is best practice as far as radio is concerned.

I will post a link to the tracker website that I will be using just before the day, but this link will let you see the few test drives that I have done in Sydney:


UpLift-1 Science Questions (Archives)

Balloon Testing UpLift-1InnerwestCourier 20111110_p07*** Recovered From Archives ***

Students get Busy with UpLift-1

We are now well engaged with one Primary School and a 3 campus college. We are hoping for more schools to come on board, but so far the results are more than satisfying.

The senior students at Leichhardt Primary School in Sydney are having a naming contest for the capsule. Y3-6 will be involved and the teachers will pick the winning student. Their picture will be placed in the capsule and sent skyward.

The students at Sydney Secondary College’s Blackwattle Bay campus have already begun to build the capsule and have participated in a workshop with me. They have also been doing some science experiments to test the materials that we will be using. More on that below.

The students at Sydney Secondary College’s Leichhardt campus will meet with me shortly for their first workshop.

The workshop outline the mission and allow students to begin with science experiments to find out what will happen during the flight and what might cause problems.

The experiments that have already been conducted at Blackwattle Bay are:

  • Testing bubble wrap at 1/100th the sea level air pressure (our thermal payload blanket)
  • Testing Styrofoam for slow decompression (for a 2 hour ascent) and then a more rapid compression (over a 30 minutes descent).
  • Testing a jig and hot wire cutter for the Styrofoam for the capsule
  • Testing a suitable glue for Styrofoam

These high school students will be making up our mission team and the Leichhardt campus will be holding a special science workshop during the morning so that student swill be able to monitor the progress of the flight and doing the science experiments on the day. There will be discussions on the tracking system and returned data. They will also get video updates on the mission before and during the flight.

I would encourage students to estimate the burst altitude from information available on the web for a Kaymont 350 gram balloon from Totex and the conditions on the day. Lower temperatures will keep the balloon aloft longer.

UpLift Weather Balloon Series (Archives)

Balloon*** Recovered From Archives ***

Posted By On 22 Aug 2011.
My name is Robert Brand and I am involved in space missions and Balloon Flights to the upper atmosphere. I don’t just read the space news and I like doing things, so Do-It-Yourself (DIY) Space was a natural. Unfortunately high altitude weather balloons don’t get into space, but they do get a long way up. Many make it over 20 miles / 30 kms and the atmosphere is so thing that it is getting close to space. My son Jason (age 9) will also be a big part of tracking and recovering the craft

The UpLift series is a record of my personal weather balloon launches in Blog form. Here you will find everything that you ever wanted to know about high altitude balloon flights, but in more of a blog form – I simply do not have the time to make it a reference site. I will try and not miss anything important and I expect that for the Australian enthusiast, there will be enough detail to even know how to approach CASA (Australia’s Civil Aviation Safety Authority) for a permit to fly. Some flights may occur outside of Australia, but if they are launches instigated by me, they will still carry the name.

The series will be numerically numbered so UpLift-1 is the first flight.

The flights will normally originate from a point in central New South Wales (NSW). They will use amateur radio tracking and where possible they will involve schools and other educational opportunities. They will carry as much scientific payload as possible and the data will be available on these pages. This will include full flight information, time, height, atmospheric pressure, etc as well as photos and videos.

We are Coming Back Online Soon

Robert brand 2013Welcome back.

My name is Robert Brand and I am involved in High Altitude Balloon (HAB) and space projects. My site went off the air due to a mistake with our ISP and I am restoring it. I expect it to be back in the next week. My apologies for the inconvenience.

I am Team Stellar’s Director for Spacecraft Communications Navigation and Data. I am also involved in many other space activities and future missions.
Interested in High Altitude Balloon Flights

We have had 16 balloon flights with 15 being commercial. All payloads have been successfully recovered. If you wish to book a commercial HAB flight for science, advertising or any other reason, please contact me here:

Our prices are reasonable and although we can never guarantee the recovery of a payload, we are the most successful in the world at recovering payloads. Our current capability is up to 4kg, but we are developing a capability to over 15kg.
