A method, computer program product, and a system where a processor(s) obtains, via a satellite sensor which continuously observes an Earth scene, geospatial product(s) (satellite derived event(s). The processor(s) associates each geospatial product with a location defined by a reference on a coordinate system. The processor(s) determines a current location of a client device on the coordinate system. The processor(s) generates proximity values to indicate a proximity of the current location to each geospatial product. The processor(s) determines if the proximity values predefined proximity thresholds and if a proximity thresholds is met or exceeded by at least one proximity value, the processor(s) generates a notification for the client device, an alert regarding a geospatial products(s). The processor(s) transmits the alert to the client device and generates an instant alert visually disrupting any application displaying on the client device.

The present invention relates to a portable directional antenna which is equipped with a camera which is integrated into the housing of the directional antenna. In addition to the conventional documentation of the position-finding information, this integrated, installed camera makes it possible, by means of the directional antenna function, to also optically document the surroundings of the interference source with a variable level of detail, for example by way long-range or short-range capture. By way of the optical additional information thus obtained, the present invention provides a simple, but nonetheless very effective, enhanced documentation option for interference sources and the surroundings thereof. Thus, during the search for radio-frequency interferences, no separate camera for capturing image information has to be brought along, and this increases the comfort for a user. The present invention further relates to a portable measurement arrangement and to a method for measuring an electromagnetic signal emitted by a source.

A mobile card reader can be configured to connect to an input module of a mobile device.
