Most of the times you would want your ground station to be stable. Secured on a metal beam on top of a building, protected, homed and zeroed where no-one and nothing could disturb it. That is the ideal situation.
For those of us though that like adventures and want to carry a ground station with us on a field trip (DXing, Iridium flare hunts or even mountaineering) having SatNOGS be portable would be a huge advantage.
Luckily (actually… by design) the main gear mechanical assembly is a lightweight box with 3 beams sticking out. Easily carried even as a backpack. Antennas can be detached and especially the yagi ones, disassembled and carried as a long beam. But where would you put your ground station on? That called for a tripod!
We did have a tripod design (v1) early on (check designs here) but it was not really easily constructed and not easily deployable. So we focused on a new design.
Version 2 is much more easily constructed, considerably more stable and totally portable as it collapses in a single beam. We tested it dozens of times on the field over the past couple of weeks and it is stable enough to allow reliable operations for a typical SatNOGS setup (UHF and VHF antennas mounted too). The cost of it? Aprox 15 USD 🙂
