A-GPS: Satellite Location Detection for Mobile Devices
GPS based location uses the transit time of signals transmitted from GPS satellites to estimate location. A-GPS adds assistance data, such as the position of the satellites at a current time, to enhance both the accuracy and time to fix of a location estimate. For customers who need a handset-based solution A-GPS is a good choice. A-GPS can be deployed in GSM, UMTS and LTE networks.
A-GPS excels in conditions where direct line-of-sight with the satellites can be maintained, including open sky conditions in suburban and rural areas. For mission-critical applications, such as law enforcement, GPS based positioning complements other geo location methods. However, by itself GPS is insufficient for such applications due to its poor performance indoors and the possibility that it can be disabled, spoofed or interfered with.
Polaris Wireless Location Signatures® (WLS) is the only highly accurate and scalable location solution that is completely plug-and-play. It does not require any additional hardware changes or additions at either the mobile phone or base station. Built on a patented implementation of the 3GPP-standardized Radio Frequency Pattern Matching (RFPM) location technique, WLS reliably and cost-effectively supports the full range of required location applications for law enforcement and government safety, across GSM, UMTS and LTE deployments.
Polaris Wireless’ hybrid location technology provides the best possible accuracy through a statistical combination of best-in-class geo-location and measurement technologies. Addressing all of today’s comprehensive application needs, the hybrid solution merges the software-only, dense urban and indoor capabilities of Polaris WLS® with the precise location capabilities of Assisted-GPS and other solutions.
