How to Connect the Juniper Systems Geode to the Trimble TDC100 Running Esri Collector

The Trimble TDC100 runs the Android OS, so it’s important that before you begin, make sure to get the Geode Connect App from the Play Store.   This app allows you to configure the settings inside the Geode.  Here are the recommended settings: Turn on the Juniper Systems Geode On the TDC100, tap the Menu […]

How to Remove “Bad” Data in Pathfinder Office Before Exporting to GIS or CAD

Try as we might to setup our data collection software correctly and use a repeatable field data collection protocol to collect high accuracy data, there’s not much we can do to prevent GNSS errors from creeping into our features. The only users who can almost avoid this are those who perform their field work in […]

How to get an AutoCAD Drawing into TerraSync as Background File

During the course of providing training for our customers who purchase a GNSS mapping system, we often get asked, “How do I get my AutoCAD drawing into TerraSync?” Depending on how AutoCAD is used, the drawing could have a known spatial reference or it could have an arbitrary coordinate system defined as the lower left […]

Should I Post Process My GPS Field Data?

The answer to this question may seem obvious. We all want to get the best data possible when using a GPS or GNSS receiver, right? So how can we accomplish that? Many of us are happy with real time corrections. But, what if real time corrections are not available? In North America, most of us […]

How to Choose a Single Base or VRS Subnet in Oregon or Washington to Receive Real Time Corrections for High Accuracy Mapping

For those of you using GNSS surveying or mapping systems in Oregon or Washington, you have access to real time correctors via cellular modem or cell phone to a comprehensive network of GNSS base stations, providing there is cellular service somewhere near your project site. VRS Information A VRS, or Virtual Reference Station, is a […]

When Deciding What Coordinate System to Use…

When deciding what coordinate system to use (or export to) after collecting GNSS data in the field with a spatial reference of Latitude, Longitude, WGS-84, HAE in meters, there’s really no “correct” one.  The decision should be based on how you want to project your data onto a map or in a computer program.  It’s […]
