26、6 - Data Sheet1.7 Precision Timing1.7.1 Time modeNEO-6T provides a special Time Mode to provide higher timing accuracy. The NEO-6T is designed for use with stationary antenna setups. The Time Mode features three different settings described in Table 3: Disabled, Survey- In and Fixed Mode. For optima

27、l performance entering the position of the antenna (when known) is recommended as potential source of errors will be reduced.DisabledStandard PVT operationSurvey-InThe GPS receiver computes the average position over an extended time period until a predefined maximum standard deviation has been reach

28、ed. Afterwards the receiver will be automatically set to Fixed Mode and the timing features will be activated.Fixed ModeIn this mode, a fixed 3D position and known standard deviation is assumed and the timing features are activated. Fixed Mode can either be activated directly by feeding pre-defined

29、position coordinates (ECEF- Earth Center Earth Fixed format) or by performing a Survey-In.In Fixed mode, the timing errors in the TIMEPULSE signal which otherwise result from positioning errors are eliminated. Single-satellite operation is supported. For details, please refer to the u-blox 6 Receive

30、r Description including Protocol Specification 2.Table 3: Time mode settings1.7.2 Timepulse and frequency referenceNEO-6T comes with a timepulse output which can be configured from 0.25 Hz up to 10 MHz. The timepulse can either be used for time synchronization (i.e. 1 pulse per second) or as a refer

31、ence frequency in the MHz range. A timepulse in the MHz range provides excellent long-term frequency accuracy and stability.1.7.3 Time markNEO-6T can be used for precise time measurements with sub-microsecond resolution using the external interrupt (EXTINT0). Rising and falling edges of these signal

32、s are time-stamped to the GPS or UTC time and counted. The Time Mark functionality can be enabled with the UBX-CFG-TM2 messageFor details, please refer to the u-blox 6 Receiver Description including Protocol Specification 2.1.8 Raw dataRaw data output is supported at an update rate of 5 Hz on the NE

33、O-6T and NEO-6P. The UBX-RXM-RAW message includes carrier phase with half-cycle ambiguity resolved, code phase and Doppler measurements, which can be used in external applications that offer precision positioning, real-time kinematics (RTK) and attitude sensing.1.9 Automotive Dead ReckoningAutomotiv

34、e Dead Reckoning (ADR) is u-blox industry proven off-the-shelf Dead Reckoning solution for tier-one automotive customers. u-blox ADR solution combines GPS and sensor digital data using a tightly coupled Kalman filter. This improves position accuracy during periods of no or degraded GPS signal.The NE

35、O-6V provides ADR functionality over its software sensor interface. A variety of sensors (such as wheelticks and gyroscope) are supported, with the sensor data received via UBX messages from the application processor. This allows for easy integration and a simple hardware interface, lowering costs.

36、By using digital sensor data available on the vehicle bus, hardware costs are minimized since no extra sensors are required for Dead Reckoning functionality. ADR is designed for simple integration and easy configuration of different sensor options (e.g. with or without gyroscope) and vehicle variant
