Support Notes detailing latest support issues.
Mapping and GIS Product Compatibility List(ProdCompMatrix_17April2013.pdf - 3830 KB)This document outlines the compatibility between Trimble field devices, versions of Trimble field software, versions of the GPS Pathfinder Office software and Microsoft Windows operating systems.
Protecting Your Equipment Against Power Surges/Spikes(MGIS_SprtNote_Protecting_Your_Equipment_Against_Power_Surges.pdf - 919 KB)Power surges/spikes can damage electronic equipment. Trimble recommends that you use a high quality surge protector to protect all electronic equipment from damage by power surges/spikes. This is especially important in locations where power supplies can be unreliable or that are prone to electrical storms.
Como proteger su equipo de picos y sobretension (Spanish)(Span_MGIS_SprtNote_Protecting_Your_Equipment_Against_Power_Surges.pdf - 250 KB)Los picos y la sobretension pueden danar el equipo electronico. Trimble recomienda que use un protector de sobretension de alta calidad para proteger todo el equipo electronico de este tipo de danos. Esto es especialmente importante en ubicaciones donde los suministros de alimentacion no sean muy confiables o en sitios propensos a tormentas electricas.
Trimble GPS Receivers: Status Update for WAAS Satellites(MGIS_SprtNote_WAAS_Update_May2008.pdf - 294 KB)This document provides an update on the status of the WAAS (Wide Area Augmentation System) satellites, including the FAA's expected timeline for the second new WAAS satellite (PRN 138) to be set as operational, and for the older WAAS satellites (PRNs 122 and 134) to be decommissioned.
This document describes the Trimble GPS receivers that are able to use the new WAAS satellites, and describes how to install a new SBAS.ini file and configure your GPS receiver to use the new WAAS satellites.
Resolving Communication Errors between the GPS Receiver and Field Software(SprtNote_ProXR-XRS_Communications.pdf - 28 KB)To ensure your GPS Pathfinder® Pro XR or Pro XRS receiver communicates correctly with your data collection or data maintenance software, you must use a version of the field software that is compatible with the GPS receiver's embedded software version. This Support Note outlines compatibilities between field software versions and the different embedded software versions of the Pro XR and Pro XRS receivers.
Characterizing Accuracy of Trimble Pathfinder Mapping Receivers(acc_sum.pdf - 376 KB)This white paper discusses performance characterization for the GeoExplorer®, GPS Pathfinder Pro XL™, and the GPS Pathfinder Pro XR™ receivers. Several real-world data sets are presented and analyzed for accuracy. The results are presented in graphs that show how point feature accuracy depends on the distance from the base station receiver and on the occupation time. This TIP will help you understand product sheet accuracy specifications and how they apply to your data. Point feature accuracy is discussed for MCORR400, the GPS Pathfinder™ Office differential correction program, and for the Phase Processor software (MCORR400 also comes with PFINDER version 3.11 as a stand-alone utility).
Correct Use of the TSC1? Data Cable(TIP_TSC1_connector_using.pdf - 26 KB)The TSC1 data cable (PN 32287-00) is designed to provide a reliable connection between the TSC1 data collector and the GPS receiver. However, the cable may be prone to damage if
incorrectly removed from the TSC1. This document outlines the correct procedure to remove this cable.
What You Need to Know About Using and Maintaining Your TDC1 Datalogger Batteries(tdc1batx.pdf - 24 KB)If you are using a TDC1 datalogger with a GPS Pathfinder? Pro XL or a GPS Pathfinder? Pro XR, you need to know how to maintain and replace the batteries, and how to troubleshoot possible problems that may be associated with the batteries. The TDC1 has two sets of batteries inside the unit and a set that it uses externally. Inside the TDC1, the first set of batteries are the internal batteries. These can be either two 9-volt batteries (standard) or a Nickel Cadmium (NiCad) battery pack (available only through a private vendor). The second set of batteries are the internal back-up batteries. The back-up batteries are two 3-volt lithium batteries. The external batteries are a set of two 12-volt camcorder batteries. This TIP includes instructions for maintaining and replacing these batteries and for troubleshooting some of the battery problems that may occur.
A New Level of Accuracy for Differential GPS Mapping Applications Using EVEREST Multipath Rejection Technology(everest.pdf - 379 KB)Trimble's Everest? multipath rejection technology provides a new high-accuracy solution for code-based GPS mapping applications. By rejecting multipath signals before computing positions, the new GPS Pathfinder Pro XR? with Everest provides up to 50% higher accuracy than previous Pathfinder mapping systems. These new systems deliver a horizontal RMS error of 35 centimeters, and a vertical RMS error of 55 centimeters on a second-by-second basis while static. Dynamic tests show even better results, with horizontal RMS errors as low as 15 centimeters and vertical RMS errors as low as 30 centimeters. Mapping area and line features with high accuracy can now be accomplished with errors consistently below 1% of the area size or line length for most features.
What You Need to Know about GPS Time and Local Time as Used by Your Datalogger and Receiver(dyltsvgs.pdf - 21 KB)This TIP provides general information about how Trimble GPS receivers and dataloggers use GPS time and local time. GPS data is recorded in GPS time, which is essentially the same as UTC (Universal Time Code). Some Trimble receivers and datalogger firmware, however, allow you to configure the local time for display purposes and/or filenaming purposes only. Thus there will be no affect on GPS data records if you reconfigure your receiver and/or datalogger firmware when there is a change in the local time, e.g., a change from Standard Time to Daylight Savings Time.
