Systems and methods for performing automated localization are provided. In one example method, a plurality of coordinates representing positions of a plurality of locations may be received. The plurality of coordinates may be from two or more different coordinate systems. The numerical values of each of the plurality of coordinates may be evaluated to determine the coordinate system to which the coordinate belongs. The coordinates may be grouped into sets of coordinates based on their determined coordinate systems. Coordinates from one coordinate system may be paired with coordinates that represent the same locations from another coordinate system. A shape matching algorithm may be used to determine coordinates from different systems that represent the same locations. A localization process may then be used to convert the coordinates of the first coordinate system into coordinates of the second coordinate system based on the paired coordinates.

A graphics-aided geodesic device is provided. The device includes an antenna for receiving position data from a plurality of satellites and a receiver coupled to the antenna. The device further includes orientation circuitry for obtaining orientation data. The orientation data represents an orientation of the apparatus with respect to a plane parallel with a horizon. The device further includes positioning circuitry for determining the position of the point of interest based at least on the position data and the orientation data. A function of the graphics-aided geodesic device may be activated in response to a distance sensor detecting that an object is within a threshold distance from the device.

Systems and methods for performing aerial photography and/or photogrammetry are provided. In one example, a path to be followed by an aerial vehicle may be generated based on a path traversed by a ground vehicle. The path to be followed by the aerial vehicle may be a path that is vertically and laterally offset from the path traversed by the ground vehicle. The path traversed by the ground vehicle may be transmitted by the ground vehicle to the aerial vehicle. Alternatively, the aerial vehicle may determine the path traversed by the ground vehicle by identifying the ground vehicle within images generated by the aerial vehicle. While the aerial vehicle traverses the path to be followed, the aerial vehicle may generate and store images of the ground or other points of interest. A photogrammetry process may be performed on an object of interest using the images generated by the aerial vehicle.

Low-noise amplifier (LNA) filters and processes for filtering global navigation satellite system (GNSS) signals are disclosed. The LNA filters can be used to down-convert a received GNSS signal to a lower frequency, filter the GNSS signal at the lower frequency, and up-convert the GNSS signal to the original frequency of the GNSS signal. The down-converted frequency can be selected based on a temperature of the GNSS signal to compensate for shifts in the frequency response of the filter due to temperature changes.
