Skylark relies on data from the Singapore Land Authority’s Satellite Positioning Reference Network (SiReNT), a nationwide grid of ground stations that provides highly accurate location information. This enables Grab to achieve lane-level precision for last-mile navigation in Singapore’s dense city environment.
Grab has launched a pilot programme with OPPO, Qualcomm Technologies, and Swift Navigation to bring lane-level GPS accuracy to its driver- and delivery-partners in Singapore.
Running since October 2025, the trial involves about 250 driver- and delivery-partners, including 60 using OPPO Find N5 devices sponsored by Grab and OPPO. Each phone runs on Qualcomm Technologies’ Snapdragon 8 Elite Mobile Platform and connects to Swift Navigation’s Skylark Precise Positioning Service, which corrects GPS signal errors in real time.
