The Earth-Moon Cam, set to demo on the LunIR mission, is a navigation tool for Cis-lunar space, allowing the spacecraft to search for the illuminated disks of the Earth and moon, triangulating its position between the two.

Reaction Wheels are used in the spacecraft to provide high accuracy attitude (pointing) control. By increasing or decreasing speed, the reaction wheel forces the spacecraft to rotate in the opposite direction, allowing the spacecraft to point at specific targets to take images or transmit data to the ground.

The nano version of the STIM210 featured a reduced housing size for better mass efficiency, as well as a more flexible connector.

Gyroscopes measure the spacecraft’s spin rate about an axis, allowing the spacecraft to precisely measure its rate of rotation, a critical component of the attitude determination and control system. The STIM210 module combines an off the shelf 3-axis MEMS IMU package with a Terran control board.

The Micro torque rod builds on the TR-400 to provide a significantly larger magnetic moment, suitable for much larger vehicles, as well as complete redundancy in a single package

The Nano torque rod provides a small formfactor ADCS actuator, used for reaction wheel momentum management and contingency ADCS pointing.

The Coarse Sensor Module integrates three important backup sensors for the ADCS system, sun sensors, magnetometers, and temperature sensors to help inform the ADCS filter. The CSM2 line also provides a built in microcontroller to alleviate processor load from the host system, and full redundancy in a single package.

The GPS Module works just like the GPS in your car — but in space. The module provides absolute position and time information to the satellite’s guidance and navigation systems allowing the spacecraft to adjust its course with confidence.

The Star Tracker is the eyes of the system, and the primary external attitude reference for most systems. The Terran Star trackers use a combination of algorithms in order to detect star fields, select the proper exposure for imaging, and provide the spacecraft with an absolute pointing reference. Multiple star trackers in different orientations can be combined to provide even better pointing performance.

Gyroscopes measure the spacecraft’s spin rate about an axis, allowing the spacecraft to precisely measure its rate of rotation, a critical component of the attitude determination and control system. The STIM320 module combines an off the shelf 3-axis MEMS IMU + accelerometer package with a Terran control board.

Gyroscopes measure the spacecraft’s spin rate about an axis, allowing the spacecraft to precisely measure its rate of rotation, a critical component of the attitude determination and control system. The CVG Gyro assembly is intended for missions with the tightest pointing requirements, and combines several 2-axis gyroscopes into a single module, providing very accurate measurements.
