Each COSMIC-2 satellite, which is approximately between the size of a standard kitchen oven and a refrigerator, will carry the following instruments at launch:
- Tri-Global Navigation Satellite System Radio Occultation Receiver (TGRS)*
This receiver provides high-quality cross sections of the atmosphere. It remotely senses temperature, pressure, moisture, and lightning formation in the atmosphere, all from space. It also measures electron density in the upper atmosphere.
- Ion Velocity Meter (IVM)**
This instrument measures ion velocity in the upper atmosphere - a key metric for space weather predictions. Measuring ion velocity, concentration, composition, and temperature can help detect the effects of geomagnetic and solar storms within our atmosphere.
- Radio Frequency (RF) Beacon**
This instrument measures total electron content in Earth’s upper atmosphere to monitor space weather.
