The Rosum TV-GPS Hybrid Positioning Module
The Rosum TV-GPS
Hybrid Positioning Module (HPM) (download the HPM data sheet) combines the indoor
accuracy and reliability of TV-positioning with the global reach of
GPS. The HPM is a single-board location module for use in
tracking and
navigation devices. Position information is determined using the best
combination of available broadcast TV and GPS signals enabling reliable
location and tracking in even the most challenging environments.
Public Safety Applications In Focus
“We have heard the voice of public safety officials and are addressing it with our 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" says Rosum CEO Skip Speaks. The Rosum HPM provides reliable location where competing technolgies cannot.
all TV Towers and all GPS Satellites In-View
Rosum TV-positioning technology leverages the global terrestrial broadcast television infrastructure to provide location information with excellent indoor and urban availability and accuracy where other location technologies fail. Terrestrial broadcast TV signals are high-power, low-frequency signals that easily penetrate buildings and urban areas. Further, TV signals are wide in bandwidth, making them robust to errors arising from multipath. Both analog and digital signals are used. The increase in the number of on-air digital TV channels enhances Rosum’s performance.
World-Class A-GPS Onboard
GPS location information is provided in the form of Global Locate's Hammerhead A-GPS Chip This world-class A-GPS chipset provides highly reliable location information when satellites are visible.
Hybrid Synergy
The HPM combines the ranging information provided by the TV and A-GPS
components to deliver reliable, accurate position fix in any
environment. While deep indoors, the HPM uses TV signals for
positioning. When the HPM moves outdoors, it will automatically
transition to a mix
of TV and GPS signals, seamlessly choosing the best combination of
signals for determining location in every micro-environment.
Further, Rosum’s hybrid TV-GPS solution 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 accuracy and availability outdoors, indoors, and even
in dense urban areas, with no local-area infrastructure required.
Rosum utilizes the broadcast TV infrastructure as a distributed network
of high-powered location beacons. This infrastructure is highly
reliable even in disaster scenarios and is robust to jamming. Broadcast
TV has demanding quality-of-service requirements and is used in the
Emergency Alert System. It is well-suited to use in safety-of-life
applications including:
- First responder tracking and location
- Law enforcement tracking
- Parolee tracking (offender monitoring)
- Asset tracking and recovery
- Indoor 9-1-1 caller location determination
