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.
GPS Pathfinder Office & GPS Analyst: Data Fails to Differentially Correct Due to Missing Base Data (Satellite PRN32 Data Missing from Base File)(MGIS_SprtNote_PFO_PRN32_LegacyFieldSoftware.pdf - 181 KB)When differentially correcting your data in the Trimble GPS Pathfinder Office software or the GPS Analyst extension for ESRI ArcGIS Desktop software, your data may fail to correct, with an error stating this is due to missing base data even though you have 100% coverage by the base station files. This may occur if you have not logged SuperCorrect data in the rover file and the rover has tracked satellite PRN32, but the base station has not. This Support Note describes the issue and how to avoid it.
GPS Pathfinder Office y GPS Analyst: ¡Error en la corrección diferencial: Al satélite PRN32 le faltan datos de archivo base!(SpanSprtNote_PFO_PRN32_LegacyFieldSoftware.pdf - 59 KB)Al corregir diferencialmente sus datos en el software Trimble GPS Pathfinder Office o en la extensión GPS Analyst para ESRI ArcGIS Desktop, es posible que tenga problemas al intentar corregir sus datos, y se muestre el siguiente mensaje de error “due to missing base data” (porque faltan datos base) incluso cuando se dispone de una cobertura completa (100%) de los archivos de estación base. Esto puede ocurrir cuando el receptor móvil rastrée el satélite PRN32, pero no se registren datos SuperCorrect en el archivo móvil porque la estación base no rastrea dicho satélite. En esta Nota de Soporte se describe este problema y cómo evitarlo.
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.
GeoExplorer Series I & II - Incorrect Date Display(MGIS_SprtNote_GeoExplorerI&II_IncorrectDate.pdf - 157 KB)Trimble® GeoExplorer® I and II handhelds running the latest software (version 2.20) display an incorrect date, which may be related to the GPS WNRO (Week Number Roll Over) that occurred on 21 August 1999. This is the date that GPS satellites had the weekly clock reset to 0 from 1024. Most GPS receivers will exhibit this same weekly count and also reset at week 1024.
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).
How to Configure Your GeoExplorer or GeoExplorer II for Real-Time Differential Correction(rtcmgeo.pdf - 58 KB)This TIP includes instructions for configuring your GeoExplorer® or GeoExplorer® II for real-time differential correction (RTCM) using five types of RTCM sources: (1) Trimble ProBeacon™, DCI by DCI Digital Communications Inc., ACCQPOINT by ACCQPOINT Communications Corp., OMNISTAR by John E. Chance and Associates, Inc., and (5) Trimble TRIMTALK™ 900/450. This instructions include which cables, special parts, or connectors you need, as well as which settings to select.
How the GeoExplorer and GeoExplorer II Allocate Memory and How to Maximize Its Usage(geomem.pdf - 18 KB)Memory on the GeoExplorer® and GeoExplorer II is limited to 192K for data storage. This TIP explains how the GeoExplorer and stores data in the memory and includes tips for maximizing its usage.
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.
How to Enter Waypoints in PFINDER and Your GeoExplorer or GeoExplorer II in the UTM Coordinate System(utmwypt.pdf - 21 KB)Waypoint creation in PFINDER™ and GeoExplorer® requires the input of both the zone number and zone letter; most users know the zone number, but are not aware that there is also a zone letter. The zone numbers indicate the east-west zone location and the zone letters indicate the north-south zone location. This TIP includes information about UTM zones and instructions for entering zone letters in PFINDER, GeoExplorer and GeoExplorer II. Note that Asset Surveyor™ datalogging software and GPS Pathfinder Office use the zone numbers but not zone letters; they use only the hemispheric designator North or South.
