ATIONS 1 Description 1 1 Introduction The Wi Fi Terminus NT 110ST Wi Fi Terminus combines GPS technology with Wi Fi transport Incorporating sister company NavSync s CW20 module with ultra sensitive GPS receiver the NT 110ST provides an 802 11b g transmission containing NMEA streams giving device location longitude and latitude and UTC time The 802 11b g supports WPA2 encryption and is fully configurable to a specific network 1 2 GLOBAL POSITIONING SYSTEM GPS The Global Positioning System GPS is a military satellite based navigation system developed by the U S Department of Defense and made freely available to civil users Civilian use of GPS is available at the user s own risk subject to the prevailing DOD policy or limitations and to individuals understanding of how to use the GPS In today s satellite constellation there are a minimum of 24 operational satellites plus several operational spares in 6 orbital planes at an altitude of approximately 22 000 km The GPS system can give accurate 3 D position velocity time and frequency 24 hours a day anywhere in the world GPS satellites transmit a code for timing purposes and also a navigation message that includes their exact orbital location and system integrity data Receivers use this information together with data from their internal almanacs to establish the precise satellite location The receiver deter mines position by measuring the time taken for these signal
