If you are going to need a repeater, here is some information.
ASSY Repeater Radio SNB900 P/N ZTN53350-90 Cost: $3995
Repeater (High Mobility) - SNB900
This kit contains an SNB900 repeater radio, a radio antenna, and the cabling required to set up an RTK base station repeater radio.
The Trimble® Site Network Base 900 is a multi-network 900 MHz radio. It can be used as an external base station, repeater or rover radio. It offers a number of outstanding features and benefits for all off-machine applications.
Feature Benefit
Internal battery delivers 10+ hours of standalone operation and uninterruptible power supply capability Works more than a full day on a single charge. If connected to an external power supply and the power goes down, it will switch to battery operation with no downtime.
Internal display and keyboard with simple user interface Allows rapid configuration without the need for a PC or controller.
Display feedback on status and troubleshooting Allows simple correction and restart if a problem arises
900 MHz operation Provides license-free operation in certain countries.
Multi-network frequency hopping spread spectrum Reduces jamming or network interference.
Base, repeater or rover mode of operation Reduces product inventory and provides more flexible operation.
Designed for reliable operation in demanding RF environments and optimized for GPS with increased sensitivity and jamming immunity, the SNB900 radio also features error correction, and a high-speed data rate to ensure maximum performance.
This rugged unit is fully sealed against dust, rain, splash, and spray for optimal reliability in all weather conditions to minimize downtime and lower overall operating costs.
An RTK base station transmits corrections over a radius (usually approximately 13 km (8 miles), although this can vary). Within that radius, there may be holes in the coverage in areas that do not receive direct signals from the base. You can use a repeater radio to extend the coverage or range of your RTK network.
There are 2 types of RTK base station and repeater layout:
Hub and spoke: The base station provides primary coverage, while repeater radios are placed at points within the radius to fill in gaps in coverage.
Staircase: One or more repeater radios are used in a line to extend the primary coverage area of the network outwards in a line.
Note: Over distance, the staircase method can cause a reduction in accuracy. | |
