"ints" relate to each other and separate discussion of them would be pointless. Simple procedures can be taken to reduce the chances of information being received by a gathering method. As was mentioned before with communication, test data or telemetry data can be encoded before it is sent. It can also be encapsulated and released for pick up. IMINT Imagery intelligence refers to information gathered by planes, unmanned aerial vehicles (UAV), and satellites. Satellites Causes of failures to gain intelligence via satellites included meteorological and human. Matters of weather play a large role in IMINT failure. While radar imaging can see through clouds, it is unlikely that a general satellite sweep could find something buried under a few feet of snow or in a frozen lake. Another problem with satellite imagery is that it is a simple snapshot in time. If the satellite that captures the image is not in a geo-synchronous orbit, there is a risk of the target not being there when the satellite passes over the area again. There is also the possibility of camouflage. For example, the entrance to an underground bunker may be camouflaged with foliage and it would take an arduous examination of the image to find the information needed. Another potential failure is a satellite being unavailable at the time needed because it is being used for other intelligence purposes, and the situation or event of interest is missed. Images can also be misinterpreted, generating misleading information and potentially supporting a bad decision. Airplanes and UAV's Airplanes and UAVs can respond quicker to requests for data collection than satellites. They have fewer issues of failure, however their failures tend to be greater in magnitude. Intelligence failure with planes and UAVs: if the craft is sent to the wrong destination then it is unlikely that the information will be collected. If the aircraft is destroyed during the mission, unless information was being transmitted at the time, then data is lost. OSINT Open source information is derived from newspapers, journals, radio and television, and the Internet. There is a growing emphasis on the use of OSINT however, there are several points where collection via OSINT can fail. Information Reliability Source reliability is one of the major points that hinders collection with this method.
