Simulation system and method for determining the compass bearing of directing means of a virtual projectile/missile firing device

Abstract: A simulation system including at least one virtual projectile/missile firing device associated to a determined position and having a movable director arranged to direct a virtual projectile/missile towards a target and an image capturer arranged to capture at least one image of a scene in front of the director. The simulation system includes a terrain database with the positions of landmarks marked, a processor arranged to process the image of the scene so as to identify at least one landmark of the terrain database in the image and the processor is further arranged to determine a compass bearing of the director based on at least the position of the virtual projectile/missile and the position of the identified at least one landmark.

STDMA collision avoidance system

Abstract: The invention relates to wireless communication systems wherein services involving two or more stations in the system may be activated automatically. Data is communicated between airborne stations (A,B) according to a TDMA protocol, where the data is transmitted in time slots organized in frames of a repeating frame structure. A link address is associated with at least one time slot, and the stations select link addresses for transmission of data according to a self-organizing transmission algorithm. Each station (A,B) broadcasts data messages of a first type (D 1 ) at a first repetition rate and receives such corresponding messages from the other stations (A,B). At least based on the received data messages of the first type (D 1 ), each station determines whether a service activation criterion is fulfilled with respect to at least one other station (A,B), for example by the other station being located within a limit distance (r A ). If the service activation criterion is fulfilled, the station (A,B) starts to transmit data messages of a second type (D 2 ), which pertain to a service that involves the station itself and the at least one other station (A,B).

Magazine, cartridge and method for launching a countermeasure

Abstract: A magazine for storing and launching countermeasures arranged in cartridges, comprising a plurality of longitudinal cartridge cases forming the magazine, where the magazine comprises a tilting means adapted to tilt the cartridge cases, such that the openings of the cartridge cases can be directed in a selected direction, and where the magazine comprises a tracking system comprising an active position sensor adapted to detect the position of an incoming object. The advantage of the invention is that a countermeasure can be directed towards an incoming object before it is launched.

Understanding Team Effectiveness in a Tactical Air Unit

Abstract: Effective team work is regarded as a key factor for success in missions performed by fighter aircraft in a Tactical Air Unit TAU. Many factors contribute to how a team will succeed in their mission. From the existing literature on teamwork, Salas, Sims and Burke [1], suggested five main factors and three supporting mechanisms for effective team work. These were proposed as the "Big Five" of teamwork. This article investigates if the model offered by Salas et al. is applicable to a TAU of fighter aircraft. Semi-structured interviews were carried out with six fighter pilots. The results of these interviews imply that the model has relevance for the teamwork in a TAU. Moreover, this paper discusses implications for the design of future decision-support systems that support team effectiveness.

Adaptative modeling of surface noise during remote distance measurement

Abstract: The invention relates to an improved method and an apparatus for navigating a craft (500) by means of remote distance measurement, for instance, via a radar altimeter. This measurement of a distance between the craft (500) and a surface (B) over which the craft (500) moves involves a measurement noise model (Ngnd(B)), which for particular geographical positions (Axy, Bxy; Cxy) designates an estimation of the surface's (A, B; C) inclination to cause measurement noise at remote distance measurement against the surface at the geographical position in question (A?xy?, Bxy; Cxy). The measurement noise model (Ngnd(A), Ngnd(B); Ngnd(C)) thereby models surfaces of varying types and kown objects being located on the surface. Relevant measurement noise models (Ngnd(A), Ngnd(B); Ngnd(C)) are taken into account based on the georaphical area within which the craft (500) is estimated to be located. The size of this area is then limited iteratively by performing multiple consecutive remote distance measurements.
