In this way, the first antenna arm 121 and the second antenna arm 122 are arranged in sequence along the length direction D1 of the casing 111 to avoid overlapping the first antenna arm 121 and the second antenna arm 122, thereby reducing the size of the housing assembly as much as possible 110 height.

Along the length direction D1 of the housing 111 , the controller 140 is located at the side of the antenna arm assembly 120 . Thereby, the height of the housing assembly 110 can be reduced as much as possible.

The acceleration signal represents the current acceleration of the trusted secure satellite terminal device. The acceleration sensor sends an acceleration signal to the controller 140 . The controller 140 receives the acceleration signal, and determines whether the trusted and secure satellite terminal device is in a stopped state according to the acceleration signal.

Specifically, when the acceleration signal indicates that the acceleration of the trusted and secure satellite terminal device within a predetermined time period (for example, 10s) is 0, it means that the trusted and secure satellite terminal device is in a stopped state.

If the trusted secure satellite terminal device is in a stopped state, the controller 140 controls the frequency of the antenna arm assembly 120 to transmit and receive communication signals to decrease. Therefore, the energy consumption of the trusted and secure satellite terminal device can be reduced, and the working time of the trusted and secure satellite terminal device can be increased.

The antenna arm assembly 120 is also used to transmit and receive positioning signals to enable the controller 140 to be used to determine the current location of the trusted secure satellite terminal device.

The identification information set in the controller 140 is the chip physical fingerprint trusted authentication information. The chip physical fingerprint trusted authentication information is generated based on PUF (physical unclonable function, physical unclonable function). In this way, the chip physical fingerprint trusted authentication information generated based on PUF is sensitive to physical detection and can resist invasive attacks. Therefore, it is difficult to clone the trusted authentication information of the physical fingerprint of the chip.

Each data exchange between the controller and the antenna circuit unit requires identity trustworthy security authentication through the identity security module. Thereby, the security of data exchange between the controller and the antenna circuit unit is improved.
