1Purpose of this document
Based on module AT command manual, this document will introduce GNSS application process.
Developers could understand and develop application quickly and efficiently based on this
document.
2Introduction
SIM7060 series module combines GNSS technology for satellite navigation. Featuring an
industry-standard interface and GNSS function, it allows variable assets to be tracked seamlessly
at any location and anytime with signal coverage.
SIM7060 series includes SIM7060G and SIM7060C, among which SIM7060G is MT2625+MT3333
and SIM7060C is MT2625+AG3331.
GNSS application provides a method to interact with a GNSS module.
