On June 29th at 22:50 UTC a scientific nanosatellite* (a 3U CubeSat) sponsored by the American National Science Foundation will be deployed into its operational orbit and begin transmitting. We are looking to the Amateur Satellite community to track the satellite and record its beacon signals and be the first to confirm operations and report in.
Timing: The satellite activates itself and begins beaconing 60-minutes after its 22:50 UTC 6/26/21 deployment.
Beacon cadence: every 30-seconds
Beacon downlink frequency: 437.405 MHz
Telemetry Rate: 19200 baud
Transmitter output power: 1 Watt
Antenna gain 2.15 dBi
Altitude: 490 km circular
Inclination: 51.6 degrees
Pre-deployment predicted Two line elements (TLEs):
1 99999U 21180.95138889 .00000000 00000-0 00000-0 0 00001
2 99999 051.6425 279.6175 0007789 261.9289 239.7719 15.23772142000052
(Post-deployment TLEs will be posted at
as soon as available after deployment.)

*The satellite is known as the Ionosphere-Thermosphere Scanning Photometer for Ion Neutral Studies (IT-SPINS, for short). Built by Montana State University in Bozeman Montana (USA) and by SRI International in Menlo Park CA, and by The Johns Hopkins University Applied Physics Laboratory, the satellite will make scientific observations of emissions from the nighttime ionosphere to study oxygen ion interactions with the neutral upper atmosphere.
