Rosum Corporation Debuts TV+GPS Hybrid Positioning Module for Homeland Security and Public Safety Markets

Rosum Corporation, the leader in reliable indoor location technology for homeland security and public safety applications, together with Global Locate, a leading producer of Assisted-GPS chips and software, announced today the general availability of the Rosum TV+GPS Hybrid Positioning Module (HPM). The HPM combines the indoor and urban reliability of Rosums TV-positioning technology with the sensitivity and accuracy of Global Locates Hammerhead A-GPS chip to deliver highly reliable and accurate location in all environments: indoor, outdoor, dense urban, and rural.

The Hybrid Positioning Module is the product of intense, dedicated work to develop and refine TV-positioning technology and then to tightly integrate it with a world-class Assisted GPS solution from Global Locate, commented Rosum CEO Skip Speaks. We have heard the voice of public safety officials and are addressing their needs with Rosums HPM. Hybrid TV+GPS 3D positioning is a vital platform technology for homeland security and public safety markets, such as first response, asset awareness for law enforcement, and offender monitoring.

The HPM integrates TV and A-GPS ranging information so that any combination of three or more TV towers and GPS satellites can be used for positioning. Rosums hybrid TV+GPS solution also enhances the performance of the A-GPS engine itself by providing it with accurate time and frequency assist information which substantially improves GPS acquisition time and sensitivity. The result is unparalleled availability and accuracy for tracking and navigation applications. Further, the HPM provides altitude information to enable reliable indoor and outdoor 3D positioning.

We are delighted that Rosum has selected Global Locates Hammerhead platform for the HPM. Our single-chip Hammerhead A-GPS solution with its long-term orbital (LTO) assistance data provides unparalleled sensitivity and reliability, and the combined performance of the hybrid TV+GPS solution is extraordinary, said Scott Pomerantz, President and CEO of Global Locate.

The HPM product and HPM Developers Evaluation Kits are available through resellers and directly from Rosum Corporation. Contact Todd Young, Director of Product and Business Development ( for details.
