Telit has released a multi-constellation receiver in the ultra-high L1 frequency band, with a 7x7x2.25 mm QFN-like semiconductor package including embedded SPI flash, RTC and TCXO. Due to its compact size, the latest generation chipset and the advanced power modes, the SE873K5 brings the benefits of low cost, small form factor and good electrical and thermal performance.

The company says that the SE873K5, an addition to its SE873 family of modules and based on AG3335 series from Airoha, is ideal for applications such as wearables, fleet tracking, and drones.

The SE873K5 simultaneously tracks and navigates all four GNSS constellations — GPS, Galileo, GLONASS and Beidou — providing GNSS information over a UART, I2C or SPI interface serial port using the NMEA Protocol.

Its low-power processing core provides several customisable power-saving modes while it also optimises current draw at module wake-up by supporting both local and server based Assisted GNSS (A-GNSS) for improved TTFF. It also incorporates Satellite Based Augmentation System (SBAS) corrections from WAAS, EGNOS, MSAS or GAGAN increase positioning accuracy.

Features of the SE873K5 include the following:

  • Frequency Bands: GPS L1, GLONASS L1, Galileo E1, BeiDou B1, QZSS L1
  • Standards: NMEA
  • SBAS (EGNOS, WAAS, GAGAN and MSAS) or QZSS L1S capability
  • RTC for efficient power management
  • Low-power modes
  • Jammer rejection
  • Local and server-based A-GPS/A-GNSS
  • RoHS compliant
  • RED/UKCA certification

“The Airoha AG3335 navigation chip series provides high performance positioning reporting and navigation system along with an advanced ultra-low-power technology that perfectly fits with the portfolio offerings of Telit,” said Meng-Hann Shieh, Senior Vice President, Airoha.

“Telit carefully designed the SE873K5 multi-constellation receiver for present and future applications that require precise accuracy in a compact form factor,” said Manish Watwani, Chief Marketing and Product Officer, Telit. “Reducing the time for acquiring a valid position is particularly critical for industrial and IoT sectors, which is why the ability to pick up signals from multiple constellations provides a competitive advantage. Our module is among the smallest GNSS integration on the market.”
