Save the date. FS#5 is planned to launch on Saturday March 14th, 2020. If the weather conditions are not right on this date, Sunday March 22 will be the backup date. Launch time will be approximately 9AM to take advantage of calm winds at ground level. The launch will likely be in one of the […]
Its been a busy season around the Squirrel Engineering labs. But silently in the background Flying Squirrel #5 (FS5) has been taking shape. Based on a whole new radio telemetry design, FS5 is using APRS to relay data back to the ground. This has some major advantages over the HF signals sent by prior flying […]
One of the goals of the Flying Squirrel #4 (FS4) mission was to stay warm. Prior Flying Squirrel flights either froze to death or appeared likely to do so had another failure not terminated the flight early. For FS4, our Squirrel carried it’s own personal heating blanket to keep warm in the sub-zero temperatures. […]
FS4 launched at 10:09am PDT into light winds. The flight followed the predicted route very closely, however the balloon burst at 83,936 feet altitude. The prediction was for 100,000 feet. Had the balloon reached the predicted altitude it would have followed the route closely to the end. When the balloon burst, it was over the […]
It looks like we will have very good flying weather. The prediction has remained about the same as prior runs and the surface winds at the time launch time 10AM PDT are light. Its a good day to fly! 73s de Don KJ6FO Please follow and like us:
Today’s prediction is more of the same. And that is good news! All systems “GO” for launch tomorrow morning. I will do one last check early tomorrow, but usually there is little change in predictions this close to launch day. Stay Tuned.. 73s de Don KJ6FO Please follow and like us:
Flying Squirrel 4 transmits FT8 data on 28.075Mhz (Normal 10m FT8 Freq + 1kc) Flying Squirrel sends telemetry data on every even minute. The telemetry is broken into four 15 second FT8 transmissions, Type 1 through Type 4. The Type1 message starts at 0 seconds and send a station ID: KJ6FO FS4 HAB Type 2 […]
No one likes a rock-solid frozen squirrel, especially the squirrel. In order to keep our pilot warm we have to find a method to stay warm but not weigh the payload down too much for our lightweight mission goals. It is cold up there. FS3 climbed to 9,100m (just under 30,000 ft) before the signal […]
The Flying Squirrel #4 payload electronics package has been built and testing has started. The electronics are similar to the FS3 hardware, but a few changes were made to produce more heat inside the cabin and to clean up the board design. FS4 has a new electric blanket that can be switched on and off […]
A brave new Squirrel – Flying Squirrel #4 It was a busy winter and spring around Squirrel Engineering HQ, but despite a lot of non-squirrel projects a lot has been happening behind the scenes on the next HAB project, Flying Squirrel #4 (FS4) This article will bring you up to date on what has been […]
