The three main reasons to choose Sequitur
Sequitur RTLS is based on proprietary UWB communication and tracking schemes exploiting the Decawave chipset, which offers outstanding performance and robustness. It benefits of more than ten years of R&D experience in localization systems, radio networks and electronics.
Not only accuracy, but a reliable solution for your localization projects.
In-Tag | Position calculation
The system can be configured as GPS-like, where each Tag is a receive-only device collecting signals from multiple Anchors.
The position can be extracted by the Tag via Wi-Fi for a centralized view using Sequitur Manager or a third-party software. UDP or serial port can be used to connect a drone, robot or AGV directly to the Tag.
Fault tolerance | Easy installation
Sequitur can be installed very quickly, especially in its InGPS configuration, since no network connections among Anchors are required (power supply only). Sequitur Manager guides you in the installation, also without the need of measuring manually the coordinates of Anchors.

Since no master nodes are present, and thanks to the self-configuration of the network, an Anchor can be switched off at run-time without issues; this guarantees an extreme robustness.
Flexible | Hybrid architecture
In-GPS Tags capable of computing their positions can coexist with small, battery-powered Mini-Tags, whose positions are computed by an external Central Unit connected to the Anchors. Different configurations and types of tags can be selected depending on the application in order to accommodate every project need.

System based on a modular and asynchronous network, without the need of neither a master node nor any form of clustering/coordination. Any addition/removal of anchors can be easily managed on the basis of future changes of the environment or application.
Fixed networks of anchors requiring a-priori planning. Any change of the anchors’ architecture needs adaptation.
Decentralized architectures (both TDOA and TWR) performing the estimation of the tag position in the tag itself, allowing fast interaction with autonomous systems (robots, drones, etc.). Position available at tag side with no external connections. Zero latency and outstanding robustness due to the lack of unreliable radio links.
Most of the UWB indoor positioning systems perform position calculation only on a central unit (server). Wireless connection necessary for navigation leads to latency and unreliability.
Architecture based on asynchronous coordination among the anchors; the failure of any anchor or of any communication link does not compromise the localization of tags.
Failure of a master anchor compromises all the cluster of anchors connected to that master. Failure of the communication network between anchors and the central unit compromises the localization.
Possibility of coexistence between powerful tags estimating their position, as done in standard GNSS receivers (InGPS) and low-complexity, small and battery-powered tags (InTracking) whose positions are computed by a central server. Infinite number of tags localized simultaneously at the maximum refresh rate. No network necessary for InGPS (fully distributed).
Complex central unit estimating the position of all the tags. Reliable network connections are mandatory for operations. The positioning refresh rate always scales with the number of tags.
Not needed for InGPS. Only Ethernet for InTracking. No additional cables, no master nodes. Fast and easy installation and low-cost infrastructure.
Necessity of cable synchronization or master anchors for wireless synchronization. Presence of clusters of anchors. Complicated deployment, high cost and network planning mandatory.
Beyond state-of-the-art localization engine. Reliable locations reported. Automatic detection of outliers and out-of-service events. Robust and automatic reset of the localization engine. Automatic neighbor anchors’ discovery and seamless handover.
Clustered networks with scarce robustness in case of failure of anchors, network or localization engine.
