ContactSCP Performance Testing Results
Using only two GSM cellular signal sources, the SCP DAIN technique was able to track a person walking deep inside a building. Without any network assistance or previous knowledge of the signal source location, DAIN produced positioning accuracies better than 1.25 meters.
SCP supports demanding RTLS applications delivering meter-level accuracy positioning capabilities and outdoors. Deployment of a Location Server, local monitoring station, and optional beacons to augment existing signal coverage provides seamless, 3-D positioning. Compared to existing RTLS approaches, SCP technology requires little or no additional infrastructure with global, regional, and local positioning
Enterprise Real Time Locating Systems (RTLS)
Since SCP technology does not demodulate received signals, an SCP sensor can use the GPS Precise Positioning Service (PPS), which is only available to users with classified cryptographic decoder keys. As a result, SCP achieves 10 times higher measurement precision over traditional Standard Positioing Service (SPS, C/A channel). This improves overall accuracy, yielding consistent meter-level positioning accuracy when atmospheric corrections are applied. With real-time network assist, SCP GPS performance delivers better than 1.25 m CEP (3-D) performance in reasonable geometry
