Abstract

The invention relates to UTC time recording, and discloses a GPS trigger type microsecond meter. The GPS trigger type microsecond meter comprises an RTK positioning module, a trigger assembly, a control end and a battery assembly, wherein the RTK positioning module is wirelessly connected with an external satellite and used for acquiring positioning information and UTC time; the trigger assembly is connected with the RTK positioning module and used for being in short circuit through a cable and triggering the RTK positioning module to record the UTC time so as to acquire UTC microsecond-leveltime; the control end is wirelessly connected with the RTK positioning module and used for receiving the UTC time recorded by the RTK positioning module; and the battery assembly is electrically connected with the RTK positioning module and the trigger assembly and used for providing electric energy for the RTK positioning module. The positioning information and the UTC time are acquired through the RTK positioning module, the trigger assembly plays a trigger role, the RTK positioning module is triggered to record the UTC time in a cable short-circuit mode, finally the UTC time recorded by theRTK positioning module is received through the control end, and therefore the UTC microsecond-level time is acquired. The GPS trigger type microsecond meter is suitable for various application scenes.

Description

technical field [0001] The invention relates to the technical field of UTC time recording, in particular to a GPS trigger type microsecond meter. Background technique [0002] The current RTK high-precision positioning module has the ability to obtain microsecond-level UTC time through satellites, but there is no trigger-based device to obtain UTC microsecond-level time. For data recording based on GPS time such as seismic wave detectors, when it is necessary to record the UTC satellite time of the analog transmitter during the test and calibration process, only the stopwatch recording method can be used. For devices that require millisecond precision, the error is large. [0003] Therefore, how to provide a GPS trigger microsecond meter to obtain UTC microsecond level time has become an urgent technical problem to be solved. Contents of the invention [0004] The technical problem to be solved by the present invention is how to provide a GPS trigger microsecond meter to...
