    Abstract: A method for controlling a GNSS receiver includes: providing a state switching criterion; obtaining at least one positioning information; determining whether to switch from a first operation state to a second operation state according to the obtained positioning information and the state switching criterion, a power consumption of GNSS receiver operating under the first operation state and the second operation state is different; the obtained positioning information includes at least one of a speed value of GNSS receiver, a satellite distribution value of GNSS receiver, a satellite signal strength value of GNSS receiver, a location identification of GNSS receiver, instant motion information from a motion sensor, or location information from a WLAN device, a Bluetooth device or a UV light sensor.

    Abstract: A firmware extension method is provided, particularly adaptable for an embedded system. Firstly, a baseline firmware image is provided with a header file. Secondly, an extension firmware image is generated based on the header file, comprising one or more extended functions. Thereafter, a callback table is generated, comprising pointers pointing to entries of the extended functions in the extension firmware image. Further, memory allocation parameters are provided. The memory allocation parameters comprise a base address where the extension firmware image starts. The baseline firmware image, the extension firmware image and the callback table are then merged to generate a merged firmware image based on the memory allocation parameters.
