8. The Initializer Bar method can be used more especially when the survey takes place in the vicinity of the base short baseline It makes use of an initializer bar also called kinematic bar mounted at the base The bar is attached to the antenna base and for a limited time the rover antenna as well The bar in fact defines a 20 centimeter known baseline length After a preset occupation time the rover antenna is moved to the rover pole taking care not to obstruct the antenna during this action Initialization in Field Approach RTK Surveying In real time surveys the position status will at all times inform you of the real status of initialization At power up the time required to get a fixed solution i e the time for the rover to get initialized is called TTFF Time To First Fix Obviously for a given baseline length the better the operating conditions low DOP large number of received satellites open sky conditions the easier the initialization and therefore the shorter the TTFF 59 Precise Surveying Field Applications amp Concepts The initialization can even be faster if there is a possibility for you to use the Known Point initialization method or if your receiver is a ProMark3 the Initializer Bar method Typical Initialization Times TTFF The charts below show the variations of the TTFF obtained with Ashtech receivers as a function of baseline length initialization method a

Rover positions at times t0 are delivered at times t1 t0 Position request times t1 Position delivery times The time when position is requested is tO and the time when the rover starts providing the position for time tO is t1 Times tOa tOe and tOj in the base and the rover are synchronous because they originate from the same clock which is the GNSS time Here the latency t1 tO is caused by the extrapolation and position processing times in the sole rover In this RTK Implementation configuration a typical latency time in Ashtech receivers is 15 ms Use Context Fast RTK should be used when consistent and high rate position updates are required such as in machine control or field operator guidance and when consistent position accuracy is not the highest priority Benefits The position output rate is less sensitive to the rate at which the rover receives RTK correction data The latency is shorter than in time tagged mode thanks to the extrapolation process The rover will continue to compute positions even if there is a minor interruption in the RTK correction data Under good conditions centimeter level accuracy can be maintained in the rover even if no RTK correction data is received for several seconds Drawback Accuracy is slightly degraded with extrapolated solutions because the corrections slowly deviate from the true correction Insensitivity of the Fast RTK Mode to Missing Base Epochs

Commands Running Serial Commands from a USB Key Serial commands can also be run from a USB key you connect to the receiver s USB port through the dedicated cable What you have to do is create a text file containing the list of serial commands you would like the receiver to execute In this file can also be inserted the PASHS CMD WTI command which is used to introduce an idle time before the receiver is allowed to execute the command that comes after After typing the last command in the file press the ENTER key to insert a carriage return line feed as the last item in the file This is mandatory Then you just have to copy the file to the USB key s root directory The receiver will always execute the list of commands the script in the given order except for some commands like PASHS REC and PASHS INI which are necessarily run last Starting the execution of the script may be done in two different ways e Automatically The receiver will automatically prompt you to run the script when you connect the USB key to the receiver This is achieved by simply naming the file autoconfig cmd e Manually This is achieved by naming the file differently and using the PASHS CMD LOD command to initiate the execution of the script Described below is the typical procedure to make the receiver run automatically a series of commands stored on a USB key under a file named autoconfig cmd e Connect the USB key to t
