Methods and systems for scheduling the transmission of localization signals and operating self-localizing apparatus
First Claim
1. A system for determining a transmission schedule for a localization system comprising a plurality of positioning anchors configured to wirelessly transmit localization signals that can be used for determining position information within a region, the system comprising:
- at least one processor configured to;
receive (a) locations of the plurality of positioning anchors, (b) at least one anchor property of the plurality of positioning anchors, and (c) positioning performance for two zones within the region, wherein the positioning performance indicates different positioning performance for each of the two zones;
determine the transmission schedule for the plurality of anchors based on (a) the locations of the plurality of positioning anchors, (b) the at least one anchor property of the plurality of positioning anchors, and (c) the positioning performance for the two zones, wherein the plurality of positioning anchors are configured to wirelessly transmit the localization signals according to the transmission schedule; and
output the transmission schedule to the plurality of positioning anchors.

Abstract
Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.
