Component of GPS signal that gets deciphered by all types of GPS receivers is
Show Hint
- Coarse-Acquisition code
- Precision code
- Link-1 frequency
- Link-2C frequency
The Correct Option is A
Solution and Explanation
- Coarse-Acquisition (C/A) code: The C/A code is a civilian-use component of the GPS signal that is used by all GPS receivers. This code is transmitted by all GPS satellites and is used by the receiver to decode the signal and calculate the position. It has a 1,023-bit length and repeats every millisecond.
- Precision code: This code is encrypted and primarily used by military GPS receivers. It is not available to all civilian receivers. The Precision code offers a more accurate signal than the C/A code but requires specialized military equipment to decode.
- Link-1 and Link-2C frequencies: These are the frequencies at which the GPS satellites communicate with the receiver. While the Link-1 and Link-2 frequencies are part of the GPS signal structure, they are not directly related to the component that all GPS receivers can decipher. These are used for more advanced, military-based applications.
Since the Coarse-Acquisition (C/A) code is the only component accessible by all GPS receivers (civilian or military), the correct answer is (A).
