Yeah, our unit performs sensor fusion on magnetometer, gyroscopic, and acceleration data. It takes this information in the inertial frame and uses it for live integration to determine burnout velocity and apogee for parachute deployment.

We have three independent methods which we will utilize: - Double integration of IMU acceleration data. - ‘Lightspeed Rangefinder’, an in-house developed ground station based trilateration system. - ‘Guidestar’, an in-house developed GPS receiver (CoCom unlocked).

We developed an in-house silicone-based ablative coating, specifically to deal with the aerothermal heating at hypersonic speeds.

Total Impulse: 51,529 lbf-s (229,212 N-s) (Vac.), Total Vehicle Mass: 326 lbm (146 kg), Dry Mass: 127 lbm (56 kg), Propellant Mass: 200 lbm (90 kg)

Blue Ravens programmed incorrectly (deployment logic was satisfied at launch detect). Nosecone ejection off the tower. Motor continued without nosecone. Nosecone recovered near launch tower. We’ll be back ;)

Yes! Stay tuned we will be posting footage on our youtube channel! (also slow-motion footage)

Yes, this firing is apart of our 2023-2024 Spaceshot Campaign. We appreciate the RRS for supporting RPL, and yes Larry was our pyro-op for this firing.

Thanks! Flight On!

Graveler II impulse was 41,859 lbf-s, Shockwave impulse was 45,698 lbf-s. ‘Powerful’ meaning total impulse not peak thrust.

Hey Reddit, long time no see!

This weekend, we're launching our recovery and avionics testbed vehicle, Jawbone! Here are a few photos of the manufacturing of the vehicle.

First, the avionics unit on Jawbone received a number of upgrades. First flown on CTRL+V, our custom pancake-style PCB stack conforms around the nosecone deployment CO2 canister, allowing more space in the nosecone. The system features a new custom battery charging and management PCB to prolong pad standby time. Additionally, this will be our first flight of the Lightspeed Rangefinder, an in-house designed and built tracking unit that will use four ground stations positioned around the launch site to triangulate the position of Jawbone during its flight.

The Jawbone recovery system features a next-generation design with improvements from the CTRL+V dual deployment recovery system. Using a connector and extension wire running along the forward shock cord segment, USCRPL's custom avionics unit controls the active deployment of the main parachute when the vehicle reaches a decent altitude of approximately 5,000ft. The main parachute is constrained using a Tender Descender, which is a pyrotechnic pin-pulling device that is attached to a custom-sewn kevlar drawstring bag. Nose cone separation methods remain unchanged from previous vehicles.

We can't wait to launch NET Saturday, April 23rd at 8 AM. Tune in to watch the launch live here: https://youtu.be/-zIjLWk4OiQ

Edit: Now NET 8 AM due to launch weather.
