Lemur-2 (6U)

OroraTech 1 [Orora Technologies]

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

The Lemur-2 payload consists of three subpayloads:

• Spire satellites, which orbit close to Earth's atmosphere, use the SENSE payload to 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 STRATOS payload enables tracking ships worldwide by receiving their AIS signals.
• The AirSafe ASD-B payload to track airplanes.

Some Lemur-2 satellites are built on 6U CubeSat busses to allow for additional hosted payloads to be accomodated.

FOREST 1 (Forest Observation and Recognition Experimental Smallsat Thermal Detector) is a prototype satellite by Orora Technologies to detect wild fires. It is the precursor mission to a larger constellation of wild fire detection satellites.

The OroraTech-1 satellite is based on an enlarged 6U CubeSat version of Spire's Lemur-2 cubesat and features customized experiments additionally to the standard Lemur payload.

It carries OroraTech’s unique and proprietary thermal-infrared camera and data processing unit designed to detect fires and transmit the data using Spire’s satellite and ground network. The technology will help identify and monitor the areas at risk of wildfires and enable early detection of wildfire hotspots.
