Simulated flight of JL3 and SL100. StratoLogger SL100 by PerfectFlite (20 samples per second) Maximum altitude of 100,000 feet ASL (per users manual) AltimeterThree by Jolly Logic (31 samples per second) Maximum altitude of 29,500 feet ASL (per users manual) Test resulted in SL100 reporting a max flight to 11,322 AGL while the AltimeterThree reported 11,383 AGL The 61 foot delta can be explained due to different sample refresh rates and an imperfect vacuum system We were happy with the results, this system proved the computer will fire at or near apogee and again at a pre-programmed lower altitude with sufficient voltage to fire a charge.
