Abstract: The present disclosure presents a method and an apparatus for communications in a non-geostationary orbit (NGSO) satellite network. For example, the method may include receiving data, at a relay node, from a first NGSO satellite of the NGSO satellite network, wherein the relay node is located at a boundary or a common beam area associated with the first satellite and a second satellite of the NGSO satellite network, and wherein the data is received at the relay node in response to identifying by the first NGSO satellite that an internet point of presence (IPP) is not available in at least one of a plurality of beams associated with the first NGSO satellite, and relaying the data from the relay node to a second NGSO satellite of the NGSO satellite network, wherein an IPP is available in at least one of a plurality of beams associated with the second NGSO satellite. As such, communications in a non-geostationary orbit (NGSO) satellite network may be achieved.

Abstract: A position location method includes receiving, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag. The method also includes transmitting, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag. The method further includes receiving, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.

Abstract: A method for ground to air communication includes receiving a first pilot signal on a first wide beam from a first ground base station by a first antenna element covering a first range of azimuth angles from an aircraft. Data is received on a directed data beam from the first ground base station by the first antenna element. A second pilot signal is received on a second wide beam from a second ground base station by a second antenna element covering a second range of azimuth angles different than the first range of azimuth angles. A signal strength of the second pilot signal is compared with a signal strength of the first pilot signal. Data reception is switched from the first antenna element to the second antenna element if the signal strength of the second pilot signal is greater than the signal strength of the first pilot signal.

Abstract: Methods, systems, and devices are described for tracking an asset or person in an indoor environment and for validating the location of the asset or person. A location of a mobile tag attached to the asset or person is estimated and various candidate spaces within the indoor environment, such as rooms or hallways, are identified from the location estimate. Fixed tags deployed within each of the candidate spaces are scheduled to transmit energy signals such that fixed tags in different candidate spaces transmit energy signals at different times. The mobile tag receives instructions to detect energy signals at the various times that the fixed tags in the candidate spaces are scheduled to transmit the energy signals. The one candidate space in which the mobile tag is located may be identified based on which of the transmitted energy signals is detected.
