Abstract: A method for coarse estimation (approx. 100 km accuracy) of a location of a terminal in a satellite communication system is disclosed. A terminal may use multiple transmissions from one or more LEO satellites and may estimate a footprint for each transmission using the transmission time and satellite ephemeris. A coarse location may then be determined by estimating an intersection region of each of the estimated footprints. The location may be determined in various ways such as using a centroid, median and optimization methods using error functions. The intersection region may also be approximated as a polygon and may be implemented using a circular buffer to maintain an up-to-date estimate. The method may be performed remotely by a satellite or core network to estimate the location of a transmitter, including non-system transmitters, and may be used as an initial input for more computationally complex signal aided location estimation.

The clamping force is sufficient to maintain the assembly and the supported overhead equipment at a desired overhead location on the pole.

Abstract: An adaptive satellite communication system uses an interference aware scheduler to select slot transmission parameters for transmitting a message. When scheduling transmission of a message by a particular terminal the scheduler determines interference parameters of any external communication systems for the transmitter location and intended transmission time period. The scheduler then uses this to estimate if a particular combination of slot transmission parameters are likely to cause interference and can then adjust the slot transmission parameters to reduce potential interference. The scheduler may use an optimisation method which is configured to select slots based subject to constraints related to latency, probability of transmission failure/success and interference.

Abstract: A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.
