Program: Lemur
S2946
US private remote-sensing program to operate a constellation of micro-satellites (3U cubesats) to provide weather data using radio occultation. It's also used to locate sources of jamming signals.
Operated by Spire Global Inc.

Ardusat 1 and Ardusat X were launched from ISS on 19 November 2013, 1U, 1 kg cubesats to fly Arduino-based processors from multiple sensors such as a magnetometer, a gyroscope, an accelerometer, temperature sensors, luminosity sensors, geiger counters, an optical spectrometer and a camera (1.3 MP). Were crowdfunded under Nanosatisfy LLc name. Decayed in April 2014.
Ardusat 2 was launched in January 2014.
Changed name for Spire Global Inc in July 2014 after raising $25 million.
In 2016, the company requested to launch and operating authority for 175 technically identical non-geostationary satellites, operating at orbital altitudes from 400 to 720 km and inclinations ranging from equatorial to polar sun-synchronous (98 degrees) to provide maritime monitoring, meteorological monitoring, and earth imaging services.
Spire would like to deploy a total of up to 900 technically identical satellites over a period of 15 years.
In March 2016, the build and launch from ISS of 9 satellites was granted, operating only in 2020-2025 MHz downlink, 402-403 MHz uplink, and to received AIS signals.
In June 2016, a further 20 satellites were authorized in orbits between 400 and 650 km. In Oct 2016 a further 28 satellites were authorized
Phase 1B
For Phase 1B satellites, downlink: 2020-2025 MHz (primary), 2200-2290 MHz (primary), 401-402 MHz (backup), and 402-403 MHz (backup).
TT&C: 399.9-400.05 MHz (Earth-to-space; primary); 401-402 MHz (space-to-Earth; primary); and 402-403 MHz (space-to-Earth & Earth-to-space; primary).
Should also receive Automatic Identification System (AIS) signals the 156.7625-156.7875 MHz (AIS 3), 156.8125-156.8375 MHz (AIS 4), 161.9625-161.9875 MHz (AIS 1), and 162.0125-162.0375 MHz (AIS 2) frequency bands, and receive Application Specific Messages (ASM) signals in the 161.9375-161.9625 MHz (ASM 1) and 161.9875-162.0125 MHz (ASM 2) frequency bands.
Phase 1C
For Phase 1C satellites, the same frequencies as Phase 1B are used plus 449.75-450.25 MHz frequency band uplink (primary) for TT&C, as well as to receive Automatic Dependent Surveillance-Broadcast (ADS-B) signals in the 1087.7-1092.3 MHz frequency band.
Phase II
Phase II satellites were authorised in orbits from 385 to 650 km, with orbits between 0° and 98°. 872 satellites are approved. Frequencies:
Data downlink: 8025-8400 MHz, 2020-2025 MHz, 2200-2290 MHz
Data uplink: 2025-2110 MHz
Data backup in 402-403 MHz
TT&C downlink: 401-402 MHz
TT&C uplink: 402-403 MHz, 449.75-450.25 MHz, 2025-2110 MHz
In addition, Spire proposes to receive AIS signals in the 161.9625-161.9875 MHz and 162.0125-162.0375 MHz frequency bands, and GPS signals centered at 1575.42 MHz and 1227.60 MHz. Will also receive Galileo signals in 1559-1591 MHz and 1164-1219 MHz to observe radio occultation.
Vega will be used to launch Lemur2 satellites from 2019 on. These are cubesat 5kg, in 500 km orbit, lifetime 2 to 3 years
