DRAFAFT Introduction The GMS-2Pro receiver is a single-frequency, GPS+GLONASS L1 receiver and hand-held controller built to be the most advanced, compact, and portable receiver for the GIS surveying market. An integrated electronic compass and digital camera make the GMS-2Pro an all-purpose, GIS field mapping unit. The GMS-2Pro receiver is a multi-function, multi-purpose receiver intended for precision markets.
Introduction and time services on a global, all-weather, 24-hour scale to any user equipped with a GNSS tracking receiver on or near the Earth’s surface: • GPS – the Global Positioning System maintained and operated by the United States Department of Defense. For information on the status of this system, visit the US Naval Observatory website (http://tycho.usno.navy.mil/) or the US Coast Guard website (http://www.navcen.uscg.gov/).
ephemerides (satellite positions as a function of time), to ensure the satellites transmit data properly. • User – The community and military that use GNSS receivers and the corresponding satellites to calculate positions. Calculating Absolute Positions When calculating an absolute position, a stationary or moving receiver determines its three-dimensional position with respect to the origin of an Earth-Center Earth-Fixed coordinate system.
Introduction measurements from each GPS satellite in view and forms the differences (corrections) between the calculated distance to the satellites and the measured pseudo-ranges to the satellites. These corrections are then built up to the industry standard (RTCM or various proprietary standards) established for transmitting differential corrections and broadcast to the remote receiver(s) using a data communication link.
– Differential positioning (DGPS and RTK) strongly mitigates atmospheric and orbital errors, and counteracts Selective Availability (SA) signals the US Department of Defense transmits with GPS signals. – The more satellites in view, the stronger the signal, the lower the DOP number, the higher positioning accuracy. • Availability – The availability of satellites affects the calculation of valid positions. The more visible satellites available, the more valid and accurate the position.
Introduction The hand-held controller component of the GMS-2Pro includes the Windows® CE operating system and color LCD touch screen. Integrated Bluetooth® wireless technology allows this system to be a cable-free controller/receiver for maximum portability. The rugged casing is durable and built for rugged use. As a field controller, the GMS-2Pro can run a full suite of field software for working with total stations and RTK GPS systems.
receiver clock and GPS time. All this information can be stored in the the optional SD card and internal flash memory, then processed using a post-processing software package. Capabilities of the GMS-2Pro receiver include: • Multipath reduction • Wide area augmentation system (WAAS) • Single-frequency static, kinematic, and differential GPS (DGPS) survey modes • Setting different mask angles • Setting different survey parameters The integrated 1.
Introduction For more details on accessories and options available for the GMS-2, contact your local Topcon dealer. Rechargeable and Backup Batteries The GMS-2 comes equipped with a rechargeable battery (GMS-2Pro Battery) for powering the unit. The battery can be charged in the unit or in an optional battery charger. A backup battery is also located in the battery pocket and the unit’s serial number is located under the battery.
• The display screen and touch panel provides a graphical and tactile user interface for the unit. • The power button turns the receiver on and off. • The ESC (escape) button exits from the current screen or function. • The ENT (enter) button applies settings, numerical values, and records points (depending on the settings of internal software). Pressing this button for one second activates the controller’s Windows Start menu.

Introduction Using the GMS-2 The GMS-2 can be used as a stand-alone, L1 GPS+ receiver, or with other devices. When installing software or performing file transfers, the USB cable of Bluetooth module connects the GMS-2 to a computer for in-office processing. For increased surveying accuracy, a connected external GPS antenna or external receiver allows other signals (such as L2 or Beacon) to be recorded.
Figure 3-1. GMS-2 System Connections Connecting the GMS-2 and a Computer Connecting the GMS-2 and a computer allows software to be installed onto the controller and data to be uploaded from the controller to a computer. When connecting the GMS-2 and a computer, Microsoft ActiveSync must be installed on the computer. See “Installing Microsoft ActiveSync” on page 2-7 for details. For a Bluetooth connection, see Connecting the GMS-2 and a Bl for details. 1.
