ODALCOM

ODALCOM is a Free-Space C Band laser transceiver specifically designed to provide small satellite platforms with high-performance optical space-to-ground communication links.

Optical communications are a candidate to overcome the limits posed by RF systems:

  • Increased security thanks to the highly spatial directivity. Difficult eavesdropping / jamming.
  • Simple and compact radiating elements, low mechanical complexity.
  • Comms hardware is small and compact.
  • Very high data rates achievable at a higher power efficiency.

Main Features:

  • Mechanisms-Free beam steering and forming.
  • 500 Mbps Tx rate.
  • Volume 1U.
  • Mass <1.5Kg.
  • Power consumption lower than 3W.
  • Optical Power: up to 1W (100 mw nominal)
  • Rich and seamless logic interface (SPI, Ethernet, I2C).
Specifications
  • Optical capabilities
    • Nominal Optical Power transmission: 200mW (23 dBm).
    • Maximum Optical Transmission Power: 1W (30 dBm).
    • Coarse pointing angular beam steering range: 15º (±7.5º), combining SLM and torque satellite actuators (reaction wheels and magnetorquers).
    • Fine pointing angular range: 5.93º (±2.97º) by optical modulation (only through SLM operation).
