Sequitur is a Real Time Locating System (RTLS).
It is an ecosystem capable of high localization accuracy thanks to the adoption of the UWB technology.
A set of fixed nodes, called anchors, is positioned in the monitored area. They are the access points of the Sequitur RTLS, and they act as reference to localize mobile nodes, called tags.
Different types of tag and architecture are offered depending on the need to localize and track people, objects, machines or provide real-time navigation.
Sequitur enables localization, tracking and navigation in harsh environments, such as industrial contexts. It works indoor and outdoor, also where GPS is unavailable.


Sequitur RTLS can deliver position in real time, anywhere and anytime.
It has been designed to cover an extremely large set of different use cases, thanks to its flexibility.
High accuracy but also the maximum simplicity of deployment, seamless scalability to cover large and complex environments with low effort, availability of management and maintenance tools, reliability of data.
Unique features to guarantee a successful achievement of your project’s requirements.

Sequitur ecosystem is composed of anchors, tags and a management software.
Different products are offered depending on the user need.
In particular, a main distinction is related to the architecture, centralized and decentralized.

The decentralized architecture

The decentralized architecture works as a GPS system, where unlimited tags compute simultaneously their positions. This architecture is suitable for navigation and to track machines, robots and drones. Power supply is required at tag side. No external servers are needed. No connection among anchors. Maximum simplicity of deployment.

Decentralized TDOA

Position estimation: in tag

Tag form factor: industrial tag for machines, external battery pack or power supply

Tag energy efficiency: typical 1 day (10Ah 5V battery pack)

Tags: Unlimited – Tracked simultaneously at max refresh rate

Refresh Rate: up to 20 Hz for all the tags simultaneously

Network infrastructure (anchors): not needed

Central unit: not needed. Available for centralized tags’ monitoring and management (WiFi)


The centralized architecture

The centralized architecture allows localization of small and battery-powered tags, whose positions are computed by an external Central Unit. Anchors are connected to the network. No master nodes are present for the maximum flexibility and scalability.

Centralized TDOA

Position estimation: in central unit

Tag form factor: small personal tag with embedded battery

Tag energy efficiency: ~ 14.000.000 position updates per battery (weeks/months, scales with refresh rate)

Tags: Unlimited – High tag density, scales with refresh rate

Refresh Rate: up to 20 Hz, scales with number of tags

Network infrastructure (anchors): Ethernet

Central unit: needed for position estimation. Possibility of coexistence of InGPS and InTracking tags


Sequitur Decentralized and Centralized architectures based on Time-Difference-of-Arrival (TDOA) can also coexist. In this manner, in the same network you can have unlimited InGPS tags computing their positions, and a large number of InTracking tags (Mini-Tags) whose positions are computed by the Central Unit.
Other solutions, such as Two-Way-Ranging (TWR) are available to cover every kind of project and requirement.


Sequitur is certified for the CE market.
