    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 in accordance with an aspect of the present disclosure includes receiving a first ranging signal from an asset tag. The method also includes receiving a second ranging signal that was transmitted a known delay after the first ranging signal. The second ranging signal is from another device. Such a method further includes computing a pseudo-range between a point of reception and the asset tag based at least in part on a time difference between the first ranging signal and the second ranging signal.

    Abstract: Methods, systems, and devices are described for tracking an asset or person using a synchronized set of anchor units. A tag attached to the asset or person has a clock offset relative to the anchor units, which in turn have clock offsets relative to each other. To remove the effect of the clock offset from the tag when estimating the location of the tag, the anchor units are synchronized by determining their clock offsets through signals wirelessly transmitted between the anchor units. The clock offsets may be obtained when there is a clear line-of-sight (LOS) path between anchor units as well as when the LOS path is obstructed. The range measurements that produce the estimate of the location of the tag are then determined from preamble information provided by the tag and from the clock offsets determined for the anchor units.

    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.
