Laser Link in Space
The CLICK (CubeSat Laser Infrared CrossLinK) mission demonstrates high-speed data transfer between two satellites in low Earth orbit using infrared lasers at 20 Mbps. By employing pulse-position modulation, the satellites encode information based on the precise timing of laser pulses, synchronized using chip-scale atomic clocks (CSACs) for nanosecond-level accuracy. This precise synchronization enables the satellites to achieve 50 cm ranging precision and reliable time-of-flight measurements, essential for future space communication networks.

CubeSat Handling of Multisystem Precision Time Transfer
CHOMPTT is emitting StenSat packets, an AX.25 UI frame sent using AFSK1200 modulation. You can help us keep track of CHOMPTT's status by uploading these packets. Listen for the beacon at a carrier frequency of 437.56 MHZ with 1200 baud AFSK modulation. There are "Bus packets" (CHOMPTT) and "Opti packets" (OPTI). Since StenSat cannot send binary data, all telemetry is encoded in ASCII85.
