CSR (Cambridge Silicon Radio) and Maestro Wireless Solutions have announced the availability of the A5100-A - A next-generation GNSS module (based on SiRFstarV™) that combines high performance GPS and GLONASS receiver technology in a small 10 x 15 mm package. The module can concurrently acquire and track the all visible GPS, GLONASS, QZSS, and SBAS satellites. Concurrent GNSS performance enables the A5100-A to choose the best satellites from different constellations and deliver optimal location information. Other benefits are better coverage, enhanced stability and accuracy in difficult environments, such as urban canyons, and stronger resilience to multipath and signal jamming. This ensures consumers maintain a position fix whether they’re in the middle of a busy city or in a remote rural location.
The A5100-A achieves unprecedented accuracy with quad-constellation support, up to 30 per cent faster Time-To-First-Fix (TTFF), and up to 20 per cent lower power consumption using CSR’s TricklePowerTM and Push-to-Fix (PtF) modes. The module also accelerates customer time to market and reduces development risks by integrating a number of components including, TCXO, SAW filter, RTC, antenna control mechanism, and flash memory for future-proof upgrades. They also offer a drop-in replacement capability for Maestro’s previous SiRFstar4 generation modules. The castellated edge form factor also enables simpler manufacturing and reduces assembly cost.
Maestro Wireless has worked closely with CSR to develop this high performance solution that is available in a small form factor essential for today’s compact devices. They have combined low power consumption with high sensitivity, high jamming immunity and concurrent GNSS operation. The A5100-A is ideal for a wide range of applications including wearable devices, cameras and automotive trackers.
