What accuracy is specified for GPS receivers in this standard?

The standard specifies the method for testing accuracy (Clause 5.2), not a specific accuracy value. The required accuracy must be defined by the user and tested according to the code's procedures.

What are the key environmental tests for a GPS receiver under IS 14902?

Key tests include Dry Heat, Cold, Damp Heat (cyclic), and Vibration tests, as detailed in Clause 5.3, which in turn refers to the IS 9000 series for procedures.

Does this standard apply to GPS modules in mobile phones?

No, this standard is intended for dedicated GPS receivers used for applications like surveying, geodesy, and navigation, not for general consumer electronics.

This standard specifies the general characteristics, performance requirements, and detailed methods of test for GPS receivers. It covers aspects like positioning accuracy, physical characteristics, and environmental durability to ensure the equipment is suitable for surveying and related applications.

Specifies general characteristics and methods of test for GPS receivers used in surveying and navigation.

Practical Notes

This code is primarily for manufacturers and testing laboratories to certify GPS equipment. End-users can reference it in procurement documents to specify required test compliance.

The standard defines *how* to test accuracy, but not the acceptance limits for different grades (e.g., survey-grade vs. mapping-grade). These limits must be specified separately by the purchaser.

Compliance with environmental tests (Clause 5.3) is critical for ensuring the receiver's reliability in harsh Indian field conditions.
