Lemur-2

Lemur 2 [Spire]

Lemur-2 is the initial constellation of low-Earth orbiting satellites built by Spire. These satellites carry two payloads for meteorology and ship traffic tracking.

The Lemur-2 satellites carry two payloads: STRATOS GPS radio occultation payload and the SENSE AIS payload.

The SENSE payload enables tracking ships worldwide by receiving their AIS signals. Spire satellites, which orbit close to Earth's atmosphere, listen for GPS satellite signals - which are impacted as they pass through Earth's atmosphere. Using a process called GPS radio occultation, Spire measures the change in GPS signal readings to calculate very precise profiles for temperature, pressure, and humidity here on Earth.

The first four more Lemur-2 satellites were launched piggy-back on a PSLV-XL rocket in 2015.

The second batch was launched with Cygnus CRS-6 to the ISS, four of the satellites to be deployed from the ISS airlock, five of them directly from the NanoRacks NRCSD-E deployer on the Cygnus vehicle. Deployment of the ISS satellites began on 18 May 2016. Four of the five other satellites were deployed on 22 June from Cygnus, but the fifth failed to deploy and reentered together with Cygnus.

The third batch of four satellites were launched on a NanoRacks NRCSD-E deployer on the Cygnus CRS-5 cargo craft to be deployed after the departure from the ISS.

A fourth batch of four was launched on a H-2B-304 with HTV 6 to the ISS to be deployed from there.

Eight more followed on a bulk Cubesat launch on an Indian PSLV-XL in February 2017.

In April 2017, four more followed on the Cygnus CRS-7 mission.

Eight more were launched in June 2017 again on an Indian PSLV-XL rocket.

Another eight were launched in July 2017 on a Russian Soyuz-2-1a Fregat-M rocket. One of these was deployed in a wrong but usable orbit.

Spire planned to launch eight Lemur-2 into an equatorial orbit on the ORS 5 (SensorSat) mission on a Minotaur-4 Orion-38 rocket, but had to be cancelled due to legal issues concerning the restriction on the use of excess ballistic missile assets for commercial payloads.

Spire announced a sencond generation series to be launched from 2018 onwards, which will also feature ADS-B payloads to track airplanes.

It is unknown, how many Lemur-2 satellites in total will be launched. The total number of Lemur satellites will be around 100, but these will be incremental updated and may feature different sensors.
