THE CHALLENGENavIC Is Now a Requirement, Not an Option
AIS 140 mandates NavIC for commercial vehicle tracking, and defense and marine programs increasingly require the Indian regional system. A GPS-only tracker no longer qualifies. NavIC is not a drop-in, it broadcasts on L5 and S-band that most GPS antennas are not tuned for, and the firmware has to acquire and report on the IRNSS constellation correctly. The requirement is NavIC-capable hardware and firmware that actually locks on, not a GPS board with NavIC on the datasheet. This build is scoped to that.
Built within the Telematics and GPS Tracking ecosystem, and frequently paired with AIS 140 and NavIC Compliance.
WHAT'S INCLUDED
NavIC From Module Selection to Lock
NavIC-Enabled GNSS Module Selection
A NavIC-capable GNSS receiver is selected to fit your power, size, and cost targets, then verified to acquire the IRNSS constellation in practice rather than on the strength of the datasheet alone.
Multi-Constellation Firmware
Firmware fuses NavIC with GPS and other constellations, manages acquisition and reporting cadence, and exposes the position and fix quality your application and compliance flow need.
IRNSS Two-Way Messaging
IRNSS short messaging is integrated where the program needs an out-of-band channel with no cellular, such as marine and remote operations, so the device can send and receive even where there is no network.
L5 and S-Band Antenna Tuning
The antenna is selected and tuned for the L5 and S-band that NavIC uses, because an L1-tuned GPS antenna will not lock onto NavIC reliably. This is the step where most NavIC bring-ups succeed or fail.
WHY RNDSQUARE
Why RNDSquare
NavIC bring-up is an RF and firmware problem, and the work sits squarely at that layer: GNSS and cellular boards designed in Altium, antennas tuned to specific bands, and multi-constellation receiver firmware brought up on tracking hardware. Antenna matching for L5 and S-band is treated as a first-class part of the design, since it is the step that decides whether a NavIC tracker acquires the constellation in the field or only on paper.
FAQ
Common Questions
Why do trackers now need NavIC?
AIS 140 mandates NavIC for commercial vehicle tracking, and defense and marine programs increasingly require the Indian regional system for sovereignty and resilience reasons. A GPS-only tracker no longer meets these requirements, so the hardware and firmware have to support NavIC from the start.
What is the difference between using NavIC for position and IRNSS messaging?
NavIC gives you positioning from the IRNSS constellation. IRNSS also supports two-way messaging, which is valuable where there is no cellular coverage, such as at sea. Both can be included: position from the multi-constellation receiver, and short messaging where the program needs an out-of-band channel.
Why does the antenna matter so much for NavIC?
NavIC broadcasts on L5 and S-band, not the L1 band most GPS antennas are tuned for. If the antenna is not matched to those bands the receiver will not lock onto NavIC reliably. The antenna is selected and tuned for L5 and S-band so the device actually acquires the constellation.
Can NavIC be added to your existing tracker design?
In most cases yes. The current GNSS module, antenna, and firmware are assessed, then the design moves to a NavIC-capable receiver, the antenna is retuned for the right bands, and the firmware is updated to acquire and report on NavIC alongside GPS.
