A receiver determines a roll rate of a spinning projectile that receives a signal from a satellite or terrestrial transmitter at a directional antenna fixed to the projectile. The receiver tracks a code phase and a rate of change thereof of the received signal relative to a local model signal corresponding to the transmitter. A roll correlator of the receiver correlates the received signal with the model signal based on (i) the tracked code phase and rate, and (ii) a roll-correlator integration time assumed to produce a predetermined number N of correlation samples per revolution of the antenna, to produce sequential correlation samples for each of successive revolutions of the antenna. The receiver determines a time difference between successive periods of observed signal reception based on the correlation samples, and determines a roll rate based on the time difference.

A munitions dispenser employs a plurality of launch tubes mounted in an array as a segmented dispenser assembly. Each tube in the array is configured to carry a selected munition releasably coupled in a cylindrical bore of the tube for substantially vertical release through a lower aperture. A frame, mountable to an air vehicle, carries the array of launch tubes. A skin covers the array of launch tubes with the skin and frame with the array configured for nested engagement of multiple segmented assemblies.

The invention relates to a method for acquiring the coordinates of a trigger point (P) of a projectile (4) above a field part (1) on which a target (5a, 5b, 5c) is located. The method is characterized in that it comprises the following steps: emission of at least one laser pulse having a pre-determined duration and directed towards the target (5a, 5b, 5c); reception of the images reflected with a receiver equipped with means for the synchronous visualization of the laser pulses originating from a piece of observation of the field part (1); recovery of the coordinates of a desired trigger point (P) when the operator has chosen a location after the piece of observation was moved. The invention also relates to a fire-control system using such a method.

Disclosed is A Global Positioning System (GPS) independent navigation system (GINS) for a self-guided aerial vehicle (SAV). The SAV has a housing, where the housing has an outer surface, a length, a front-end, and a longitudinal axis along the length of the housing. The GINS may include a first optical sensor, second optical sensor, storage unit, and comparator.

Multiple LRSWs are launched to place at least one follower LRSW in a trailing position to at least one lead LRSW in a lead wave. Knowledge of the target space and particularly the primary target gained by the lead LRSWs is transmitted to the follower LRSWs (either directly or via another communication platform such as a satellite or UAV) and incorporated by the follower LRSWs to inform target selection. The follower LRSWs in the following wave trail the lead LRSWs in the lead wave with sufficient spacing in time and distance to inform target selection and with range remaining to maneuver to the selected target. This knowledge may be transmitted back to another follower LRSW (together with any data acquired the initial follower LRSW) and so forth in a string of LRSWs to inform target selection and maneuver the LRSWs to the primary target or an alternate target.
