    Data can be stored on a 3.3 V or 5 V-compliant CompactFlash data card, which can be accessed, exchanged, and replaced when needed. The GSR2600 can store data to the card automatically, according to pre-configured parameters, without any user intervention. In applications when continuous user interaction is required, a data collector can be used with the GSR2600.
  • Page 21 General Components Chapter 3 You can swap data cards while the GSR2600 is on, providing that data logging is not in progress. If the card is accidently removed while data is logging, (or if you experience a power interruption or similar disruptive event), the GSR2600 may lose several seconds, up to a maximum of one minute, of data.
  • Page 22 If you are unsure if the data card is actually logging data, look at the top right corner of the display in the LCD screen. If the word “LOGGING” is flashing, then data is currently being recorded. For more information, see Section 5.5, LCD Front Panel, Page 37. GSR2600...

    Note: Exceptional conditions may delay the acquisition of satellites beyond the start of the logging session. It is important to remember that as long as the GSR2600 is connected to batteries, the GSR2600 is drawing power. When left unused, the GSR2600 will drain the batteries completely after five to ten days.

  • Page 39: Insufficient Power

    CAUTION The GSR2600 may also become inactive if the external power input is greater than the power specified. See Section 1.6, GSR2600 Usage Cautions, on Page 6 for more information.

  • Page 89: Scheduled Data Collection

    You can schedule your GSR2600 to collect data repetitively (For example, every day from 15:00 to 17:00), or customized (For example, tomorrow from 10:00 to 11:00 and the day after from 17:00 to 18:00).

  • Page 90: Handheld Data Collection

    When you connect the data collector to the receiver, a communication link is established and the handheld controls the behavior of the receiver. If you turned on the GSR2600 by pressing its power button, the POWERUP configuration (if it exists) will run until the data collector takes control of the receiver.

  • Page 91: Defining Data To Be Collected

    You can define what type of information should be collected during a data collection session by using tools available in the Sokkia Planning software to create configurations for the GSR2600. The following sections give an overview of using configurations. For more information, refer to your Planning Reference Manual.

  • Page 92: Using The Powerup Configuration

    7.2.2 Using the POWERUP configuration The GSR2600 receiver initially operates on a default configuration called POWERUP (for more information on configurations, see Section 7.2, Defining Data to be Collected, Page 83, or refer to your Planning Reference Manual).

  • Page 94: Auto-Generated File Name Convention

    When scheduling a single data collection event, you can provide a name for the data file in advance. If you are scheduling a series of events, you must allow the GSR2600 to generate names automatically. All files have a *.pdc extension, and must consist of one to eight characters.

    Vibration (Random Profile) The GSR2600 can acquire and track satellites while undergoing vibration levels as shown below. It assumes that C/No > 45 dB-Hz and that the GSR2600 is in high-dynamics mode. Assuming appropriate mounting, the GSR2600 conforms to random vibration templates for RTCA/DO-160C, Section 8.6.2 (Curve C template), MIL-STD-202F, Test Condition I (Letter A nominal template), and ASAE EP455, Section 5.15.1 nominal template.

When this voltage drops below 6.5 V DC, the battery is unusable, and the GSR2600 will switch to the next available battery. Once battery reserves are depleted, the GSR2600 shuts itself off.

  • Page 100 Complies with the radiated and conducted emission limits for a Class B digital device, for both CISPR 22 and Part 15 of the FCC rules. For full details see GSR2600 FCC and CE Notice on Page 2. a. Accuracy depends on number of satellites visible, obstructions, satellite geometry (DOP), occupation time, multipath effects, atmospheric conditions, baseline length, survey procedures, and data quality.

    True North (0 degrees) typically, and a chosen point. Baseline - The three-dimensional vector distance between a pair of stations for which simultaneous GPS data has been collected and processed with differential techniques. The most accurate GPS result. GSR2600...
  • Page 102 GPS receivers within the same general geographic area. Differential positioning - Determines the relative coordinates using two or more receivers that are simultaneously tracking the same satellites. Dynamic differential positioning is a real-time calibration technique achieved by sending corrections to the GSR2600...
  • Page 103 This is related to GDOP. It describes the NDOP (North Dilution effects of geometry on the northern of Precision) component of positioning accuracy. Doppler - The change in frequency of sound, light or other wave caused by movement of its source relative to the observer. GSR2600...
  • Page 104 GPS receivers. Available as "broadcast ephemeris" or as post-processed "precise ephemeris." Epoch - Same as measurement time epoch. The local time at which a GPSCard takes a measurement. For example, 15 seconds, 30 seconds. GSR2600...
  • Page 105 Geoidal Separation (or Geoidal Height) - The height difference between the ellipsoidal height and orthometric height at a given point on the earth’s surface. Worded differently, it is the separation between the geoid surface and the ellipsoid surface at a given point on the earth’s surface. GSR2600...

  • Page 107 (C/A) code, as well as encrypted P-code, and navigation, messages used by commercial GPS receivers. L2 - A secondary GPS carrier, containing only encrypted P-code, used primarily to calculate signal delays caused by the ionosphere. The L2 frequency is 1227.60 MHz. GSR2600...
  • Page 108 Obstruction - Physical feature that blocks the satellite direct line of site from the point of observation. GPS signals are very weak. They can be blocked from reaching the GPS antenna by objects between the antenna and the satellites. Classic examples of obstructions are trees and buildings. GSR2600...
  • Page 109 Pseudolite - An Earth-based transmitter designed to mimic a satellite. May be used to transmit differential corrections. Pseudorange - The calculated range from the GPS receiver to the satellite determined by taking the difference between the measured satellite transmit time and the receiver time of GSR2600...
  • Page 110 Root-Mean-Square (RMS) - A statistical measure of the scatter of computed positions about a "best fit" position solution. RMS can be applied to any random variable. Rover - The GPS receiver that moves from site to site during a kinematics GPS survey. GSR2600...
