CellGuide has announced the availability of its patent-pending HiMap technology for precision urban positioning. HiMap is now commercially available for CellGuide's ACLYS chip, ACLYS IP Core, and GPSense engine.

HiMap is also available for licensing as an add-on to GNSS receiver manufacturers.

HiMap significantly improves GNSS navigation performance in urban canyons. City skylines create particularly demanding operational conditions for GPS receivers.

Line-of-sight blockages and erroneous measurements adversely affect the accuracy of GNSS device positioning, tracking and navigation.

CellGuide's HiMap technology boosts GNSS receiver accuracy and availability in built-up areas.

Based on high-resolution, worldwide digital elevation mapping (DEM), HiMap serves as an additional beacon for better navigation accuracy with four or more received satellites, and true 3-D navigation with three received satellites.

HiMap enhances GNSS receiver positioning for diverse applications including vehicle and pedestrian navigation. Of particular note, HiMap advanced compression provides global urban coverage in a compact database of only a few megabytes.

"Our multi-beacon SNAP technology ensures an enhanced user experience for location-based applications. HiMap is an impressive innovation on our technology roadmap." said Boaz Efroni Rotman, CellGuide's VP Sales and Marketing.

"We continue to add beacons to our positioning engine to ensure industry-leading precision in outdoor navigation and indoor applications."
