The factory defaults are also applied when you perform a full reset of the receiver because resetting the receiver deletes the power-up files. When starting any of the SPS receivers as a base station or rover receiver using the HYDROpro software, the settings required for those operations are automatically set and configured in that software. To change the receiver settings for special applications or for use with third-party software, use the Browser interface or the Configuration Toolbox software. 20 SPS351 Modular GPS Receiver Getting Started Guide Troubleshooting This section describes some possible receiver issues, possible causes, and how to solve them. Please read this section before you contact Technical Support. Issue The receiver does not turn on Possible cause External power is too low. Solution Check the charge on the external power supply, and check the fuse if applicable. 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. 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 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. 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. An Internet server that manages authentication and password control for a network of VRS servers, and relays VRS corrections from the VRS server that you select. A radio wave having at least one characteristic (such as frequency, amplitude, or phase) that can be varied from a known reference value by modulation. [. . . ] SBAS is based on differential GPS, but applies to wide area (WAAS/EGNOS/MSAS) networks of reference stations. Corrections and additional information are broadcast using geostationary satellites. 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.
