A 6U CubeSat with APRS Digipeater for global amateur intercommunication.

Also active on UHF 437.850MHz while telemetry data inactive. Optical Visibility Investigation: A student-led study of space-to-ground optical signal acquisition using an onboard modulated beacon. S-Band Telemetry: High-bandwidth downlink at 2405.0 MHz for students to monitor optical payload performance and learn S-band link management. GNSS Reference: Uses the L1 1575.42 MHz signal to provide positioning and clock synchronization for all amateur radio payloads.

Public Participation: Encourages the amateur community to decode unencrypted telemetry and participate in link-budget validation. 1. VHF Digipeater for APRS 145.825MHz, 1200bps AX.25. Call sign BN0YCA, or ARISS also available to response. 2. UHF Telemetry 437.850MHz, 1k2 AFSK with AX25 3. S Band telemetry backup downlink using 100kbps on initially, or up to 2Mbps data rate GFSK based on ground control.

Planning a SpaceX launch from Vandenberg NET mid March 2026 into a 510 km SSO, so far moved to 29th Mar 2026.
