CSR and Maestro Wireless Solutions Launch High Performance, Low Power and Small Form Factor GNSS
New A5100-A Module is Ideal for Bringing Asset Tracking, Automotive and Wearable Devices to Market Quickly 2014-08-13 21:38:01
Hong Kong, Hong Kong SAR and Cambridge, UK – August 13, 2014 – Hong Kong based Maestro Wireless Solutions, a leading manufacturer of location receivers, and CSR plc (LSE: CSR; NASDAQ: CSRE), a global provider of innovative silicon and software solutions for location-aware applications, announce the immediate availability of the A5100-A, a next-generation SiRFstarV™ Global Navigation Satellite Systems (GNSS) positioning module that combines high performance GPS and GLONASS receiver technology in a small 10 x 15 mm package. The A5100-A is ideal for a wide range of applications including wearable devices, cameras and automotive trackers.

The A5100-A is the first release within Maestro’s new line of GNSS receivers. It achieves unprecedented accuracy with quad-constellation support, up to 30 percent faster Time-To-First-Fix (TTFF), and up to 20 percent 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 features including, TCXO, SAW filter, RTC, antenna control mechanism, and flash memory for future-proof upgrades, as well as, offering 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 for many years to design and commercialize highly accurate and reliable location products,” said Anthony Murray, Senior Vice President, Business Group at CSR. “But to win in today’s highly competitive consumer electronics market performance isn’t enough. That’s why we’ve worked with Maestro Wireless to develop a solution that excels in a range of performance metrics but also offers the small form factor essential for today’s compact devices and is highly integrated to help them get to market fast.”

Supporting all currently deployed GNSS, the A5100-A acquires and tracks 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. Immediate 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 is perfect for customers designing highly integrated products that need uncompromising performance but are pressured by the speed required to go-to market and lack of development resources,” said Olivier Bernard, EVP of Business Development at Maestro. “By combining low power consumption with high sensitivity, high jamming immunity and concurrent GNSS operation, and with its drop in upgrade path to the A2200-A, the A5100-A creates a fast and convenient route to the latest GNSS offering in the marketplace, to meet these needs quickly.”

The A5100-A offers a range of other valuable features including:

- Direct to Battery connectivity: Connects directly to a rechargeable 1.8V-3.6V Lithium battery enabling system cost reduction and increased power efficiency.

- Low Power technology: Optimized for power consumption by incorporating CSR’s breakthrough PtF technology. PtF rapidly establishes a valid position fix enabling the module to hibernate for longer periods of time, and adaptively changes power depending on the operating environment and motion conditions. Advanced algorithms and a powerful on-chip DSP processor maintain high accuracy (QoS) while achieving the lowest power level possible for the given environmental and motion conditions.

- InstantFixTM Extended Ephemeris (EE): Accelerates TTFF for devices without internet connectivity such as cameras and wearable devices, by autonomously predicting EE for as long as three days and up to 31 days when connected to a network that supports SiRFInstantFixTM server generated extended ephemeris data (SGEE).
Samples and evaluation kits are now available from Digi-key, Mouser and RichardsonRFPD. Detailed information and technical documents can be found at, and by contacting a local Maestro sales representative or authorized distributor.
