    Topcon Positioning System’s GB-1000 (Figure 1-1) is a dual-frequency, GPS+ receiver built to be the most advanced receiver for the surveying market. The GB-1000 can receive and process both L1 and L2 signals, improving the accuracy of your survey points and positions.

  • Page 18: Gps Surveying

    Post-Processing Surveying Post-processing surveying involves recording observation data to the GB-1000's built-in memory, downloading the observation data into a computer using data download software (such as, Topcon Link), and analyzing the data using post-processing software to obtain precise baseline vector information (such as, Topcon Tools).

  • Page 19: Guidelines For Post-Processing Surveying

    GPS Surveying Guidelines for Post-Processing Surveying While conducting a survey for post-processing, follow these guidelines: • Receivers that post-process must do so simultaneously. • Receivers that post-process must do so in the same or common epoch intervals. Static Surveying Static surveying is the most precise surveying method. With static surveying, the antenna is fixed at a point by means of a tripod or some other anchoring device.

  • Page 20: Rapid Static Surveying

    As with the other surveying methods, observation can be conducted simultaneously using multiple rovers and a shared reference station. With Stop & Go kinematic surveying, extremely short static observation (Stop) and a moving observation (Go) are repeated, GB-1000 Operator’s Manual...

  • Page 22: Getting Acquainted

    The GB-1000 can be built with internal memory for recording survey data, and recorded data can be downloaded using the USB, ethernet, or RS232C port. A compact flash card slot allows data to be easily copied from the built-in memory and read on a computer.

  • Page 31: Setup And Connections

    Remove this sheet NOTICE before use. A slight current flows inside the GB-1000 even when power is off. Therefore, if storing the GB-1000 for a long time with the batteries installed, the batteries will run down and the GB-1000 may become inoperable.

  • Page 32: Charging The Bt-60Q Batteries

    • When the batteries are not used for a long time, completely charge them once every 15 days, and keep them in a place with a temperature no greater than 30°C. Should a battery completely discharge, its performance will decline and fully charging it will become impossible. GB-1000 Operator’s Manual...
  • Page 33 Connecting and Charging the Batteries • During charging, the charger may become hot. • Recharging a battery immediately after charging it may cause it to deteriorate. • Do not conduct one charging immediately after another. This could cause the battery and/or the charger to deteriorate. If successive charging is necessary, let the charger rest for about 30 minutes before proceeding.

  • Page 34: Charging With The Ac Adaptor

    Charging status varies depending on the state of the batteries and power switch. • If the AC adaptor is connected when the GB-1000 is turned off, charging-on-the-run will begin once the receiver is turned on. Charging status (the percentage to which charging has taken place) can be checked using the status icons (the alternating display of the battery icons and the AC cord icon).
  • Page 35 RAPID STATIC and Batteries KINEMATIC Figure 2-4. Display – Charging Status with GB-1000 Turned On • With power turned off and the AC adaptor attached, the status icons blink between the batteries only and the AC adapter (Figure 2-5). When charging completes, power automatically switches off.

  • Page 36: Battery Charging Order And Precautions

    When both batteries are installed, the battery with the smaller remaining capacity is charges first. • When powering the GB-1000 from a car battery, the car battery may not supply a sufficient voltage charge. To ensure proper battery charging, use the AC adaptor.

  • Page 37: Icons Displayed For Bad Batteries

    Connecting and Charging the Batteries Icons Displayed for Bad Batteries If, when the batteries are being charged with the AC adapter, an abnormality related to voltage or to the charging situation occurs, the battery status icons will indicate that something is wrong with the battery.
  • Page 38 • If the abnormality display occurs for both the battery icons, or if the abnormality display occurs even after a battery is replaced, the problem may lie with the GB-1000. In this case, please contact Topcon or your local distributor.
