Due to the excessive dependence on terminal performance, traditional GPS technology integrates satellite scanning, acquisition, pseudo-range signal reception, and positioning calculations into one terminal. This results in defects such as low positioning sensitivity and large terminal power consumption. The CDMA positioning technology simplifies the work of the terminal and transfers the most arduous tasks such as satellite scanning and positioning operations from the terminal side to the positioning server on the network side. The terminal's positioning accuracy, sensitivity, cold start-up speed, and terminal power consumption are improved.
In the situation that neither the GPS satellite signal nor the wireless network signal can be separately located, the CDMA positioning system will combine the two information sources. As long as there is one satellite and one cell site, the positioning can be completed, solving the problem that cannot be solved by the conventional GPS. The infrastructure aids of the CDMA positioning system also provide 20 dB higher sensitivity than conventional GPS positioning. The improved performance enables the GPSONE hybrid positioning method to work in the depths of modern buildings or between urban buildings. Both traditional programs are usually not working in these places. CDMA positioning technology combines wireless network-assisted GPS positioning and CDMA triangulation positioning to improve indoor positioning. Positioning by CDMA triangulation can make up for positioning without satellite signals. Other cellular telephone networks such as GSM/GPRS have similar self-positioning techniques. However, because CDMA is the only network that is synchronized across the entire network (via GPS), positioning accuracy is not high.
