Abstract

The invention relates to a batch automated testing method for a navigation terminal receiver. The batch automated testing method mainly aims at batch navigation receiver testing tasks and quick batch test for batch production of the navigation terminal receiver. Without involvement of an operator or many operators, the batch automated testing method has the advantages of high accuracy, consistency, efficiency and low cost and the like and is mainly applied to analog simulation generation technique of satellite navigation signals, bussing technique, assembly line based testing technique, sampling technique and database storage technique and automatic generation technique of test result report forms.

Description

technical field [0001] The invention relates to the field of testing of navigation terminal receivers, in particular to a batch automation testing technology and sampling testing technology of navigation terminal receivers. Background technique [0002] With the continuous development and maturity of satellite navigation technology, the change trend of navigation terminal receiver test task requirements mainly includes: the number of navigation terminal receivers to be tested is gradually increasing, the types of navigation terminal receivers to be tested are increasing, and the number of navigation terminal receivers to be tested is increasing. Navigation terminal receivers need to test more and more technical performance indicators, the accuracy of test results is higher and higher, the test efficiency of each link in the test process is more and more demanding, and the test cost is limited. From this, the performance requirements and breakthrough points of the new navigat...
