A5100-A

Concurrent GNSS Receivers

a5100-300x217

 

The A5100-A is a high-sensitivity concurrent GNSS receiver that integrates Qualcomm’s SiRFstarV technology into a single, compact and easy to integrate SMT device.

By supporting simultaneous GLONASS, GPS, QZSS and SBAS measurements with the industry’s best sensitivity engine, the highest accuracy, ground tracks and fastest time-to-first-fix (TTFF) are ensured even under tough operating conditions.

Overview for A5100-A

Markets

Concurrent GNSS receiver

The A5100-A will track and follow GPS and GLONASS systems concurrently. Dual reception of GPS and BeiDou or even concurrent GLONASS and BeiDou reception is still possible by setting up the parameters. Our fine tuned signal reception and sophisticated software algorithms improve availability and accuracy in urban canyon environments.

Pin-to-pin compatible with A2200-A

This A5100-A is pin-to-pin compatible with the Lantronix A2200-A. Power, ground and dedicated pins are at the same location across device densities in order to adapt to your current design.

Lowest tracking power consumption

SiRFaware’s advanced low power management modes, high level of integration and multiple communication ports in a small form-factor makes the A5100-A suitable for a broad spectrum of GNSS applications where performance, cost and time to market are prime considerations.
