CASES SM-211 GPS-Based Space Weather Monitor Receiver

ASTRA’s CASES SM-211 GPS receiver represents a significant advance in dual frequency GPS-based space-weather monitoring. ASTRA’s proprietary tracking algorithms provide superior stability and robustness during high scintillation periods. What further differentiates this receiver from the others is

  • the programable RF front end, which offers full control over receiver behavior, products and cadences, and
  • this receiver is a "stand-alone system" with an on-board computer.

Performance comparisons show the stability and robustness of ASTRA’s GPS tracking algorithms. Compared to competitive units, the ASTRA CASES (Connected Autonomous Space Environment Sensor) SM-211 GPS space weather monitor is the most reliable receiver available for maintaining data acquisition when it matters most – tracking through intense scintillation.

In competitive studies, ASTRA's instruments have proven to be more effective at maintaining satellite lock through severe scintillation – when data needs are most critical to vital systems — thus providing a more complete data set for analysis, prediction, and modeling.

The CASES SM-211 was designed to do the following:

  • Fast logging (100 Hz)
  • Dual-frequency stand-alone system - no additional computer required
  • Superior tracking through scintillation events
  • Cost-effective solution enables deployment of arrays of CASES receivers
  • Remote programming / reconfigurability via RF front end

Unparalleled Tracking Performance in Scintillating Environments
The SM-211 GPS receiver has been developed as a cost-effective space weather instrument for monitoring ionospheric scintillation and total electron content. The receiver implements several proprietary processing techniques that make it well suited for space weather monitoring:

  • Data-bit prediction and wipe-off for robust tracking through scintillation.
  • A differencing technique for eliminating local clock effects.
  • An advanced triggering mechanism for determining the onset of scintillation.
  • Data buffering to permit observation of the prelude to scintillation.
