Telit Releases NavIC-Enabled SL869T3-I GNSS Module

Designed to support the Indian NavIC (formerly IRNSS) constellation L5 signal simultaneously with GPS L1 and SBAS, the Telit SL869T3-I GNSS module is the new multi-constellation member of the company’s SL869 family of modules.

The SL869T3-I is equipped with special HW and SW to support navigation on L1 and L5 bands. It can navigate using GPS L1, IRNSS/NavIC L5 and the GAGAN L1 SBAS systems concurrently, according to the company.

SL869T3-I is provided with a single RF input for L1 and L5 bands and multiple communication ports using UART and I2C interface. The embedded flash memory allows onboard AGPS storage, FW upgrades and customization.

The embedded TCXO ensures stable top-level performances over the whole temperature range.

The RF frontend has an additional LNA and a SAW filter specifically designed to comply with sensitivity specification contained in AIS-140 standard.

The module has been designed to be footprint compatible with SL869-V3 / V2. However, the SL869T3-I cannot be considered a drop-in replacement as supporting the L5 band on the host application could requires some additional changes on RF front-end layout as well as a new L1/L5 antenna.

It is designed to provide an optimal solution to those customers aiming to design tracking applications in compliance with AIS-140.

Additional features:

  • 1PPS output
  • UART& I2C interfaces
  • 16 x 12.2 x 2.4 mm LLC package
  • Supply voltage range: 3.0 to 3.6 VDC
  • Easy integration in AIS-140 applications
  • AGPS support via Extended Ephemeris injection as well as Extended Ephemeris on-board generation for fastest TTFF
