General specifications for low-orbit satellite-borne GNSS survey receivers
1 Scope
This standard specifies the technical requirements, test methods, and inspection rules for low-orbit satellite-borne Global Navigation Satellite System (GNSS) survey receivers
And signs, packaging, transportation, storage, etc.
This standard applies to the development, production, testing, use and inspection of low-orbit satellite-borne GNSS survey receivers. Others used in low-orbit space
The GNSS measuring receiver of the device can also be used as a reference.

3 Terms and definitions, abbreviations
3.1 Terms and definitions
The following terms and definitions defined in GB/T 39267 and QJ1947 apply to this document.
3.1.1
Capture sensitivity
The receiver is turned on when the approximate position, approximate time, ephemeris and almanac are unknown, and the navigation signal is captured and the minimum required for normal positioning.
Low signal level.
3.1.2
Antenna gain
The ratio of the radiation intensity of an omnidirectional antenna when the radiation intensity of the antenna in a given direction is the same as the input power.
Note 1.If the direction is not given, it refers to the direction of the maximum radiation intensity of the given antenna.
Note 2.If the antenna has no loss, it means that the absolute gain of the antenna in a given direction is the same in value as its directivity coefficient.
Note 3.Usually expressed in decibels.
3.1.3
Antenna phase center
An electrical center of the antenna refers to the curvature of the curve where the isophase plane of the radiation field in the far area of the antenna intersects the plane passing through the antenna axis
