Abstract

The invention discloses an energy optimization navigation unit based on combined navigation, which comprises a navigation module, a computation module, a control module and a display module. The navigation module, the computation module and the display module are connected with the control module, and the navigation module is further connected with the computation module. The energy optimization navigation unit is a handheld energy optimization GNSS (global navigation satellite system) receiver based on an inertial navigation device, and the handheld energy optimization GNSS receiver integrates advantages, including high precision, low power consumption, high independency and external interference resistance, of the inertial navigation device and a common GNSS receiver. On the premise of guaranteeing the navigation precision and sensitivity, the power consumption can be reduced to be 21% of the original power consumption. In addition, compared with the pure inertial navigation device, the energy optimization navigation unit can effectively control accumulated errors on the premise of keeping low power consumption and low dependency on external environments.

Description

technical field [0001] The present invention relates to a navigation device, in particular to an energy-optimized navigation device based on integrated navigation. Background technique [0002] Navigation technology is a technology that uses the information provided by satellites / sensors and other devices to quickly and correctly guide the carrier to the intended destination through calculation. Navigation technology was first used in the military field, but with the development of science and technology, navigation technology has gradually moved from the military field to the civilian market. Modules with navigation functions are now installed in ships, cars and even mobile phones. These navigation modules greatly facilitate people's travel. At present, in addition to the more popular satellite navigation and inertial navigation, starlight navigation and geomagnetic navigation are also emerging navigation technologies. [0003] In actual engineering applications, inertia...
