Technical Field

[0001] The utility model relates to the field of navigation technology, in particular to a coordinate positioning device. Background Art

[0002] An EPIRB that only has GPS is often referred to as a satellite EPIRB. When a ship or offshore platform sinks, the EPIRB automatically floats to the surface and sends a distress signal, which is then relayed to a ground station via the COSPAS-SARSAT system.

[0006] According to the above technical solution, the conductive metal part electrically connects the conductive metal layer and the shielding plate, so that the lower half and the shielding plate form a shielding cover for the integrated circuit board inside, and the antenna is located outside the shielding cover. In this way, the integrated circuit board will not interfere with the antenna. Moreover, the antenna is based on the shielding cover, which can improve the directivity of the antenna and improve the accuracy of positioning.

[0011] The conductive metal member is a V-shaped structure formed by bending a metal sheet. The conductive metal member is located on both sides of the shielding plate and abuts against the outer wall of the frame bracket. During installation, the antenna is fixed to the upper half of the housing, and the shielding plate and frame bracket are connected to the upper half.
