The invention discloses a portable satellite signal enhancement device which comprises a triangular cone signal enhancement mechanism, a cuboid support and a telescopic bolt lifting mechanism, wherein a connecting ring at one end of the telescopic bolt lifting mechanism is fixedly connected with a connecting hole bolt of a connecting block of the cuboid support; a connecting ring at the other end of the telescopic bolt lifting mechanism is fixedly connected with the triangular cone signal enhancement mechanism. An adjustable nut frame is adjusted so that the angle of the direction of an opening of the triangular cone signal enhancement mechanism can be adjusted. Compared with the prior art, the portable satellite signal enhancement device has the advantages of being convenient to carry, fast to install and detach, easy and convenient to use and capable of enhancing the reusability of a satellite signal device. Because the direction height angle and the azimuth angle of the satellite signal enhancement device can be adjusted, the portable satellite signal enhancement device is suitable for radar satellites with different orbit altitudes, and the usability range of a traditional satellite signal enhancement device is widened.
