Telit Introduces its Most Compact GNSS Receiver, the SE873K5

Telit’s new SE873K5 multi-constellation GNSS receiver is the smallest form factor in the company’s SE873 family of modules. Featuring the latest generation chipset and advanced power modes, it can be used in a variety of applications including wearables, fleet tracking and drones.

The receiver is based on the AG3335 series from Airoha and can simultaneously track and navigate GPS, Galileo, GLONASS and Beidou constellations, providing GNSS information over a UART, I2C or SPI interface serial port using the NMEA Protocol, according to a news release. The receiver is in the ultra-high L1 frequency band, with a 7x7x2.25 mm QFN-like semiconductor package including embedded SPI flash, RTC and TCXO.

The receiver features a low-power processing core that offers several customizable power-saving modes. It also optimizes current draw at module wake-up by supporting both local- and server-based Assisted GNSS (A-GNSS) for improved TTFF, while Satellite Based Augmentation System (SBAS) corrections from WAAS, EGNOS, MSAS or GAGAN increase positioning accuracy. The internal flash memory allows firmware updates and customization, as well as ephemeris predictions storage.

Other features include jammer rejection, RED/UKCA certification and RoHS compliance.

“Telit carefully designed the SE873K5 multi-constellation receiver for present and future applications that require precise accuracy in a compact form factor,“ Telit’s Chief Marketing and Product Officer Manish Watwani said, according to the release. “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.”
