Methods and systems for scheduling the transmission of localization signals and operating self-localizing apparatus
First Claim
1. A localization system, comprising:
- a plurality of positioning anchors configured to wirelessly transmit localization signals capable of being used by self-localizing apparatus within a region to determine position information, wherein;
a first positioning anchor of the plurality of the positioning anchors is configured to wirelessly transmit first localization signals;
a second positioning anchor of the plurality of the positioning anchors is configured to wirelessly transmit second localization signals;
a third positioning anchor of the plurality of the positioning anchors is configured to wirelessly transmit third localization signals; and
each of the plurality of positioning anchors is communicatively coupled to at least one scheduling unit, wherein the at least one scheduling unit is configured to;
schedule the transmission of the localization signals to control positioning performance within the region by;
scheduling the first positioning anchor to transmit the first localization signals at a first transmission rate;
scheduling the second positioning anchor to transmit the second localization signals at a second transmission rate; and
scheduling the third positioning anchor to transmit the third localization signals at a third transmission rate, wherein the first transmission rate is greater than the second transmission rate to provide greater positioning performance within a portion of the region.

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.
