R10 Getting Started Guide Introduction The R10 receiver incorporates a GNSS antenna, receiver, internal radio, and battery in a rugged light‐weight unit that is ideally suited as an all‐on‐the‐pole RTK rover or quick setup/rapid mobilization base station. LEDs enable you to monitor satellite tracking, radio reception, data logging status, Wi‐Fi status, and power. Bluetooth wireless technology provides cable‐free communications between the receiver and controller.
In some countries, the unit can be used without obtaining an end‐user license. Other countries require end‐user licensing. For licensing information, consult your local Trimble dealer. The R10 receiver is capable of transmitting data through Bluetooth wireless technology. Bluetooth wireless technology operates in license‐free bands. Before operating a Trimble receiver or GSM modem, determine if authorization or a license to operate the unit is required in your country.
radio is safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as on aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio. For GSM/GPRS radio Safety. Exposure to RF energy is an important safety consideration.
The antennas that can be used (country dependent) with the: 450 MHz radio are 0 dBi and 5 dBi whip antennas 900 MHz radio are 0 dBi antennas To reduce potential radio interference to other users, the antenna type and its gain should be so chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. Battery safety Removable lithium‐ion battery WARNING – Do not damage the rechargeable Lithium‐ion battery.
Connecting the receiver to a vehicle battery WARNING – Use caution when connecting battery cable's clip leads to a vehicle battery. Do not allow any metal object or jewelry to connect (short) the battery's positive (+) terminal to either the negative (‐) terminal or the metal of the vehicle connected to the battery. This could result in high current, arcing, and high temperatures, exposing the user to possible injury.

Base Applications Base station operation guidelines This topic introduces the concept of base station operation, provides information to help you identify good setup locations, describes best practices for setting up the equipment, and outlines the precautions that you need to take to protect the equipment. Real‐Time Kinematic (RTK) operation provides centimeter‐level accuracy by eliminating errors that are present in the GNSS system.
You can use either type of receiver in a permanent, semi‐permanent, or daily quick setup configuration. If semi‐permanent or permanent operation is required, however, the modular receiver delivers significant advantages. Base station setup guidelines For good performance, observe the following base station setup guidelines: Place the GNSS receiver in a location on the jobsite where equal range in all directions provides full coverage of the site.
radar transmitter can overwhelm the receiver circuits. This does not harm the receiver, but can prevent the receiver electronics from functioning correctly. Low‐power transmitters, such as those in cell phones and two‐way radios, do not interfere with receiver operations Do not set up the base station directly beneath or close to overhead power lines or electrical generation facilities. The electromagnetic fields associated with these utilities can interfere with GNSS receiver operation.
Common ways to set up a base station Trimble recommends that you use either a tripod and tribrach setup, or a fixed height tripod. The fixed height tripod is quicker and easier to set up over a control point. Take great care to ensure that the GNSS antenna is set up accurately over the control point, and that the GNSS antenna height is measured accurately, in the right way (vertical or slope height) to the right location on the antenna (base of antenna or to a specified location on the antenna).
Outputting corrections using an TDL450/HPB450 radio‐ modem The TDL450/HPB450 radio comes with a 5‐pin Lemo to 7‐pin Lemo connector with a power connection lead: 1. Connect the 7‐pin Lemo connector to the connector on the receiver. 2. Connect the 5‐pin Lemo connector to the TDL450/HPB450radio. 3. Connect the DC power lead to an external power source. 4. Turn on the TDL450/HPB450 radio. To configure the system, do one of the following: Use the Trimble Access software to connect to the receiver.
Press for 30 seconds after the receiver is turned on. (When you use this method, all data is deleted.) Use the Data Transfer utility. Use the web interface (Data Logging menu). Upgrading the receiver firmware Your receiver is supplied with the latest version of the receiver firmware already installed.

The Software Upgrade window appears again with a message that the operation was completed successfully. 9. To select another operation, click Menu; to quit the WinFlash utility, click Exit. If you click Exit, the system prompts you to confirm. 10. Click OK.
Rover Applications Setup Operation Guidelines Rover operation guidelines Real‐Time Kinematic (RTK) operation provides centimeter‐level accuracy by eliminating errors that are present in the GNSS system. For all RTK, Location RTK, or DGPS operations, you require both a rover receiver and a source of corrections from a base station or network of base stations.
The antenna and cabling should be installed where they will not become energized as a result of falling nearby power lines, nor be mounted where they are subjected to over‐voltage transients, particularly lightning. Such installations require additional protective means that are detailed in national and local electrical codes. GNSS satellites are constantly moving.

The Kalman selection works substantially better than a Least Squares solution in a mobile vehicle when there are frequent satellite signal dropouts around bridges or high buildings, and gives improved performance around forested areas. A Kalman solution uses the time history of the position and velocity it has created, whereas a Least Squares option does not use the time history. Trimble recommends that you use the Kalman filter.
If there are multiple correction streams within any one of the three categories, the selection is made by the following rules in order: 1. Use the CMR Input Filter and RTCM Input Filter. 2. Use the user‐defined Correction Controls. 3. If the category is RTK, use CMRx over CMR+™ over RTCM 3 over RTCM 2 (RTK). 4. If streams are of the same types, use the lowest RefStnId. 5. If the sources are identical, remain with the currently used channel.
