Advantech Wireless Introduce RF Converters for Satellite Tracking and Navigation

Advantech Wireless has introduced new Satellite Tracking and Navigation (STAN) dual-frequency converters that are designed specifically for applications that require two-channel coherent signal processing, such as telemetry, tracking and control (TT&C) and Low Earth Orbit (LEO) Tracking & Navigation. STAN Converters, available in C, X and S-Band variants, are built upon the latest RF conversion technology with an emphasis on spectrum purity.

Housed in a 1RU shelf, each converter contains two independent block converter modules (up or down) that are both phase-coherent and phase-matched. Setup and fault monitoring are achieved either remotely via a full-featured monitor and control platform or locally using user-friendly front panel menus. Also included are independent I/O attenuators and sample ports.

Key features of the converters include:

  • Dual L to X or Dual X to L block converters in single 1RU
  • Coherent Phase tracking between each channel over time
  • Gain tracking between channels
  • Phase matching between channels
  • Low Phase Noise
  • Low Spurious levels
  • Independent Input and Output attenuators
  • Internal/External 10 MHz with Autosensing
  • Front panel control (local)
  • Input / Output Monitoring ports for each channel
  • Full remote control (remote) via Ethernet with SNMP V1

Global Satellite Navigation Systems (GNSS) pose a number of unique challenges for ground stations. The lack of an on-board atomic clock coupled with the fact that the trajectory and speed of LEO satellites are both dynamic and subject to tracking errors, poses the need for periodic correction. With independent phase and gain-matched channels plus low phase noise, STAN Converters can add and subtract coherent signals to identify tracking errors. Corrections can then be applied, yielding a massive reduction in location errors. This is an extremely beneficial feature for complex 5G+ Satcom unmanned navigation systems.
