Smallest size in industry and innovative design with 12.9cm X 11.2cm. Using Aeronautical material Magnesium alloy with sophiscated industrials: light weight, resistance to external impact and shock absorption, and good electromagnetic shielding.
Intelligent platform provides an excellent solution for the interaction between the receiver and user, such as management, voice broadcast, and self-inspection
The internal tilt sensor helps to survery without leveling the receiver, in order to improve survey efficiency. Tilt angles is allowed up to 30°. Built-in tilt compensator corrects the coordinates according to the direction and tilt angle.
The internal electornic bubble sensor can display the leveling status of the receiver on the controller in real time. You don’t even need a leveling bubble on the pole anymore.
Equipped with Bluetooth 4.0 module, which supports receiver to work seamlessly with smart phone, tablet from Bluetooth 2.1 to 4.0, and also making Bluetooth communication faster and more stable. NFC is also available for fast connection.
Pacific Crest BD970 GNSS mainboard is a compact multi-constellation receiver designed to deliver centimeter accuracy to a variety of applications. Including GPS L2C and L5, GLONASS L1/L2 signals, and also Galileo and BEIDOU signals for improving accuracy and speed of positoning.
Integrated with powerful data-link system, T66 is compatible with major radio protocols in the market from 410-470MHz, The protocol can switch between TRIMTALK and SOUTH protocol as needed.
Static GPS survey has been used on control surveys from local to statewide extent.In static GPS surveying the receives is motionless for a time. Usually a relatively long occupation. If a static GPS control survey is carefully planned, it usually progresses smoothly.
Real Time Kinematic is a technique used to enhance the precision of position data derived from satellite-based positioning systems such as GPS , GLONASS, Galileo, BEIDOU,providing real-time corrections with up to centimetre-level accuracy. With T66 base and rover, cupled with integrated RX/TX radio or an external radio,you can realize precise large-scale RTK survey. You can also combine T66 as rover or base with a non-SANDING GNSS receiver with same protocol as a flexible solution.
A Continuously Operating Reference Station(CORS) network is a network of RTK base stations that broadcast corrections,usually over an Internet connection. Accuracy is increased in a CORS network,because more than one station helps ensure correct positioning and guards against a fales intialization of a single base station. With T66’s high compatibility on GSM/GPRS modem,you can connect to CORS network so as to optimize your working range and mobility.
