The invention relates to the technical field of
drone anti-trap measures, and particularly discloses a low-cost
drone anti-trap
navigation system. The low-cost
drone anti-trap
navigation system comprises a
satellite locating
system and an
inertial navigation system, and the
satellite locating
system can receive navigation signals of
multiple frequency points of multiple
satellite navigation systems (a Beidou and a GPS) to enable the functions of navigation telegraph text
demodulation, measurement value extraction and the like and has a timing function; according to index requirements of the
measurement precision, the range, the encapsulating performance, the
impact resistance, the temperature drift and the like, the
inertial navigation system completes style selection of an MEMS sensor; the inertial
system is built to achieve a strapdown solving information comprehensive
processing module of the posture, the position and the speed, wherein a telegraph text and measurement data of a navigation satellite are processed, detecting and removing false interference signals are achieved, and a normal
navigation function of a drone is enabled. The low-cost drone anti-trap navigation systemhas the advantages that the
navigation system with the anti-trap function is applied to the drone, a 'firewall' is formed for the drone with a police purpose, security safeguard, security protection and
transportation surveillance, so that law breakers have no opportunity to take
advantage of.
