SAT-LOA-20151123-00078 E S2946Grant of Authority Effective Date: 04/07/2017Launch and Operating AuthoritySpire Global, Inc.Nature of Service: Earth Exploration Satellite Service, OtherOn April 7, 2017, the Satellite Division granted in part and deferred in part, with conditions, the application, as amended (File No. SAT-LOA-20151123-00078, as amended by SAT-AMD-20161114-00107), of Spire Global, Inc. Specifically, Spire was authorized to construct, deploy, and operate 4 satellites to be deployed from the Cygnus cargo vessel at orbital altitudes no greater than 500 km, as part of what Spire describes as Phase IB deployment. The satellites will be used to conduct maritime monitoring and meteorological monitoring operations. The satellites will operate using the 402-403 MHz (Earth-to-space) and (space-to-Earth) frequency band for telemetry, tracking and command and back-up data downlinking, and the 2020-2025 MHz (space-to-Earth) and 2200-2290 (space-to-Earth, for 1 MHz bandwidth operations with earth stations outside the United States) frequency bands. The satellites will also receive Automatic Identification System (AIS) and Application Specific Messages (ASM) signals in the 156.7625-156.7875 MHz, 156.8125-156.8375 MHz (space-to-Earth), and 161.9625-161.9875 MHz, 162.0125-162.0375 MHz, 161.9375-161.9625 MHz, and 161.9875-162.0125 MHz (Earth-to-space) frequency bands, and GPS signals centered at 1575.42 MHz and 1227.60 MHz (space-to-Earth) frequency bands. Action was deferred on the remainder of Spire's application, as amended.
3Cat-4The 3Cat-4 team is composed of students from the University Politècnica de Catalunya in Spain.Their mission aims to demonstrate capabilities of nanosatellites for Earth Observation using GNSS-R and L-band microwave radiometry as well as for Automatic Identification Services (AIS).CELESTAThis CubeSat comes from the University of Montpellier, France and will monitor the LEO environment and perform in-orbit testing of a radiation monitor and a single event latch-up experiment. EIRSAT-1This project is a joint collaboration between University College Dublin, Ireland and Queens’ University Belfast, Northern Ireland. The team aim to test a novel gamma-ray detector module and an experiment with thermal coatings for spacecraft. ISTnanosat-1This CubeSat project is the first from Instituto Superior Técnico, Portugal. The CubeSat team will use their CubeSat to test an ADS-B receiver that aims to track aircraft in flight.LEDSATThe LEDSAT team are from Sapienza – University of Rome in Italy, and plan to improve and test new technologies for tracking of LEO satellites using LEDs.UoS3This CubeSat is the first from the University of Southampton in the United Kingdom. Their CubeSat will obtain position and attitude data for the validation of atmospheric models and space object re-entry prediction software.
Excellent article on Planet (labs). Feel free to copy to Planet's thread as I can't locate it.Chris we need a directory or index. www.bloomberg.com/news/features/2017-06-29/the-tiny-satellites-ushering-in-the-new-space-revolution
Accion Systems Ion drives. May have covered them earlier on this thread. They are now going into production and have proved themselves on a test flight.On latest Tmro space show.http://www.accion-systems.com/
