Congratulations to ISRO on today's PSLV launch which put another 20 spacecraft into orbit. Three of these satellites carry Sinclair Interplanetary attitude sensors and actuators.
SkySat-C1 has the first two ST-16RT2 new generation star trackers to fly. We eagerly await telemetry to determine just how much extra performance the improved optics will provide. It also has the first four RW3-1.0 reaction wheels giving it the torque required for rapid re-targetting. Rounding out the suite, it has the last magnetic torque rods built at Sinclair Interplanetary before the product line was licensed to SpaceFlight Industries.
M3MSAT has six RW-0.06 reaction wheels arranged as two redundant triads, along with three dual-wound magnetic torque rods. It also has the last six SS-411 digital sun sensors built at Sinclair Interplanetary before the product line was licensed to NewSpace Systems.
CLAIRE (GHGSAT-D) has three RW3-0.06 reaction wheels and an ST-16 star tracker. This is the first star tracker to fly with the RS485+CAN build option, connected to a CAN digital communications bus.
ETA: Thomas theorizes that this is the first (and likely last) single launch to carry the entire Sinclair Interplanetary product line: magnetic torque rods, reaction wheels, sun sensors and star trackers. I believe he is correct.
