4.7. Typical link calculations
Very low navigation signal levels around −133 dBm are expected over the targeted region. In addition to the nominal channel noise, these signals may also experience interference from other GNSS signals in these bands. This interference level may be minimized with the help of BOC modulation and CDMA access scheme. The receiver will also receive propagation impairments such as channel attenuation, scintillation, multipath etc. and these effects should be considered to obtain the effective signal condition at the receiver. A typical link calculation in the allocated navigation frequency is shown in the table below.
| Types of Signal | Units | Values |
| Frequency | GHz | 1.57542 |
| Wavelength | m | 0.1904 |
| EIRP | dBw | 23.00 |
| Range | km | 20,000.00 |
| Path loss | dB |
