Rocket Lab launches new constellation-class star tracker

Rocket Lab USA, Inc. (Nasdaq: RKLB) reports that a new class of star tracker, the ST-16HV, is now available for commercial use, expanding the Company's Space Systems catalogue of products for the global satellite market.

The new ST-16HV star tracker is an attitude determination sensor based on Rocket Lab's existing high-performance ST-16RT2 star tracker that has been evolved for mass manufacturing. The change results in a more affordable star tracker that is mass producible to meet the short lead time needs of both commercial and government satellite constellation projects.

By using the same electronics and electrical interface and much of the same mechanical design as the heritage star tracker, the ST-16HV can be used in its place as a responsive small satellite solution, especially for satellites and constellations in low Earth orbit.

"Rocket Lab's Space Systems Division has made tremendous strides in developing new technology and products and the new ST-16HV star tracker is the latest to join a long list of reliable and trusted space components," said Brad Clevenger, Vice President, Space Systems. "This new mass-produced star tracker will be a game changer in fulfilling the growing demand from satellite constellation customers and will be made at the Sinclair by Rocket Lab facility where we already mass produce reaction wheels."

The ST-16HV star tracker is the latest new satellite component announced in 2023, after the Frontier-X satellite radio and constellation-class 12Nms reaction wheel assembly were released in February.

The ST-16HV star tracker joins the Company's existing heritage space systems components including reaction wheels, separation systems, radios, flight software, ground software, and solar power solutions. Rocket Lab has more than 100 star trackers on orbit, including on the Defense Advanced Research Projects Agency's (DARPA) Mandrake 1 and Mandrake 2 satellites and Rocket Lab's in-house designed and built Lunar Photon spacecraft which supported NASA's Artemis program that delivered the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat to orbit the Moon.

Improving the accuracy of orbit prediction and position error covariance prediction
Beijing, China (SPX) Apr 04, 2023
With continuous developments in the space industry, the space near the earth was occupied by a variety of spacecraft whose number is increasing dramatically every year. To avoid a collision, huge computation power was spent to determine the possibility of a collision between two space objects. However, there were various uncertainties in the collision prediction process, which aggravated the burdens on space safety management. Since the collision probability was usually applied to evaluate the dangerous ... read more
