Abstract: Disclosed is a GNSS receiver, including a state monitoring sensor and a processor. The state monitoring sensor is configured to monitor a state of the GNSS receiver, and generate a first triggering signal according to the state of the GNSS receiver. The processor is configured to switch from a resting operating state to a wake-up operating state according to the first triggering signal, and transmit position information about the GNSS receiver to a remote server at a preset frequency. Further disclosed is a GNSS device.

Abstract: An LED light source capable of projecting a set graphic logo and a red dot sight thereof, comprising a point light source (1) and a peripheral light source (2) around the point light source (1), the peripheral light source (2) being discontinuous line light source. The LED light source capable of projecting the set graphic logo does not need a raster being matched with transmission to obtain an LED with luminous set graphic logo, so that the power consumption is reduced, system design is simplified, product functions are increased, and simplification of structure, convenience of operation and reduction of cost for red dot sight are facilitated.
