Check pinouts with multimeter to ensure internal wiring is intact. Ensure that the antenna has a clear line of sight. Replace the cable. External power is not properly connected. Faulty external power cable. Receiver is not tracking any satellites GPS antenna does not have clear line of sight to the sky. The cable between receiver and the GPS antenna is damaged. Cable connections at receiver or antenna are not tightly seated, or are connected incorrectly. Check all cable connections. The receiver is not responding Receiver needs a soft reset. Receiver needs a full reset. Turn off the receiver and then turn it back on again. Press for 35 seconds. The SPS Modular receiver cannot be set up as a base station using the SCS900 software The SPS Modular receiver may have been purchased as a rover receiver rather than with the optional base station capability. Ask your local dealer to check the Option Bit settings, else check the setting yourself using the WinFlash utility. If required, upgrade the receiver. SPS351 Modular GPS Receiver Getting Started Guide 21 Glossary 1PPS almanac Pulse-per-second. A pulse is generated in conjunction with a time stamp. This defines the instant when the time stamp is applicable. A file that contains orbit information on all the satellites, clock corrections, and atmospheric delay parameters. The almanac is transmitted by a GPS satellite to a GPS receiver, where it facilitates rapid acquisition of GPS signals when you start collecting data, or when you have lost track of satellites and are trying to regain GPS signals. The orbit information is a subset of the ephemeris/ephemerides data. AutoBase technology uses the position of the receiver to automatically select the correct base station; allowing for one button press operation of a base station. It shortens setup time associated with repeated daily base station setups at the same location on jobsites. In construction, a base station is a receiver placed at a known point on a jobsite that tracks the same satellites as an RTK rover, and provides a real-time differential correction message stream through radio to the rover, to obtain centimeter level positions on a continuous real-time basis. A base station can also be a part of a virtual reference station network, or a location at which GPS observations are collected over a period of time, for subsequent postprocessing to obtain the most accurate position for the location. Source of RTCM DGPS corrections transmitted from coastal reference stations in the 283. 5 to 325. 0 kHz range. BINEX is an operational binary format standard for GPS/GLONASS/SBAS research purposes. It is designed to grow and allow encapsulation of all (or most) of the information currently allowed for in a range of other formats. [. . . ] The signal strength of a satellite is a measure of the information content of the signal, relative to the signal's noise. The typical SNR of a satellite at 30° elevation is between 47 and 50 dBHz. The satellite skyplot confirms reception of a differentially corrected GPS signal and displays the number of satellites tracked by the GPS receiver, as well as their relative positions. The NTripCaster maintains a source-table containing information on available NTripSources, networks of NTripSources, and NTripCasters, to be sent to an NTripClient on request. [. . . ]
