Why it is needed

In communication, electric power, military and other fields, it is necessary to synchronize the working hours between various terminals, and the smaller the error of satellite time service function, the better.

The satellite is about 36000KM from the ground, and the typical value of navigation satellite signal is about

-133dBm. With the distance getting closer, the signal strength of several W power jammers may be millions of times higher than that of satellite signals.

The whole world has been covered by electromagnetic signals with various frequencies and intensities, and various terminals will be interfered by various electromagnetic signals, which seriously affects the communication effect between satellite signals and ground stations and various terminals.

The ground environment is complex, and satellite signals are often blocked and reflected by mountains and buildings.There may be hundreds of meters of "positioning drift" phenomenon, and accurate positioning cannot be carried out.

Navigation and timing failures can lead to a range of risks, including but not limited to loss of control of autonomous driving systems, malfunction of control terminals, abnormal operation or failure of equipment, and a series of corresponding consequences.

Below are some real cases for reference.

SONON

Threats of PNT lost

Xi'an:The positioningandauxiliary positioning system of unmannedaerial vehicle(UAV)suffered directional interference after take-off, resulting in abnormal data of its position and altitude.

Dongguan: Hundreds ofdrones were temporarilyaffected byair traffic control signals.

Year 2023, Israel launched retaliatory airstrikes in retaliation against Hamas "Al- Aqsa Flood" action, imposing large-scale restrictions on GPS signals in the corresponding areas, and then initiating ground military operations.

Year 2015, the drone flying at high speed lost its signal and fell and hurt people.

Year 2017, hundreds offishing boats went out to sea andcould not get GPS signals,which led to theirearly return to the harbor.
