Teseo: Tracking Time and Space While Saving Time and Space

Category articles

What job do GNSS (Global Navigation Satellite System) modules, such as the Teseo family of goods, play IoT? That is a basic question since in 2021, ST will expand the Teseo-LIV series. The forthcoming components will address low-power programs and multi-band options for IoT and domestic markets. Furthermore, a brand new family of modules, also called Teseo-VIC3x, will target the automotive sector. As a result of a embedded dead-reckoning program and on-board detectors, it is going to provide a totally new feature-set. It’s thus crucial to check at the condition of this business as well as the present solutions the Teseo apparatus supply engineers as we all await the modules to get there.

This blog article can be crucial because The business raves about sub-gigahertz networks, 5G, so many different protocols which it will become vital to assist experts understand the area of GNSS in this context. Are there any difficulties that no additional kind of apparatus can resolve? With this exposition, we’ll utilize the Teseo-LIV3 household for instance. The devices are little (9.7 millimeter x 10.1 mm x 2.5 mm) and encourage each of major-satellite constellations. Even the Teseo-LIV3F comprises 16 megabits of flash for information logging and firmware updates. ST can also be offering the Teseo-LIV3R, that comes with no flash memory to decrease the bill of stuff.

Teseo and Its Own GNSS Software
The Engineer’s Nightmare

Some Engineers face a challenging design challenge: supplying an accurate, streamlined, and cost-effective monitoring system. For example, if tracking the geolocation of a fleet of business vehicles, an LPWAN is too imprecise to be helpful. In the same way, some strength monitoring devices need to offer accuracy and also be small enough to fit in tight spaces. This previous use case is a distinctive sort of nightmare for most designers. Not just should they create a placement system, however they need to design a customized PCB, develop a dependable RF execution, pass regulatory certificates, and much more . The Teseo modules are so unique since they treat everything.

An Expansive Ecosystem


Teams may Begin working with a Teseo-LIV3x by catching a test board, such as the EVB-LIV3x and also even the X-NUCLEO-GNSS1A1. Together with this Teseo applications , The programs allow the fast production of some proof of the concept. Even the PC utility can aid with information visualization in addition to testing scripts. The pre-programmed modules conserve some time by easing certification surgeries. Along with the purpose bunch FP-SNS-AGNSS1 comprises a precompiled binary for your 32L496GDISCOVERY plank , therefore running a demo program that showcases the skills of this Teseo-LIV3 is as simple as dragging and dropping a document.

We advocate that engineers never start their program from scratch because that the X-CUBE-GNSS1 bundle includes roughly 80 percent of the code programmers need to benefit from this Teseo-LIV3. Likewise using these modules, teams gain from great performances, using a sexy time to first fix (TTFF) shorter than two weeks. This standard measures how much time it can take for your GNSS module to figure its location after being away for a minumum of one hour. Even a TTFF of less than two moments stays among the finest in the business.

Teseo and Its Time Applications
Locating an Atomic Clock

Another Basic challenge that lots of engineers confront revolves round true timing. In sensitive programs, such as a mobile antenna, exact logging of particular time events is vital. In the same way, some financial programs rely on maintaining an specific moment. A couple of microseconds of discrepancies could have enormous monetary consequences. In a number of these scenarios, a nuclear clock could be perfect, but that it could be overwhelmingly costly. The second best thing is, thus, to utilize a nuclear clock without needing to build a single. It is in this time as this a module such as the Teseo-LIV3 beams bright.

Utilizing Teseo to Track Time


When A GNSS module computes its worldwide standing, it pings three satellites. By calculating the time that it requires for every one of them to react, the part determines three distinct space radii that intersect at the same stage: its geographic site. Thus, to calculate their latitude and longitude, Teseo modules should correctly track time by communication using a satellite which is based in a nuclear clock. Consequently, many engineers utilize a Teseo-LIV3 element because of the own capabilities. Really, as a result of the internal processing, the difference between the time mentioned from the satellite and the timing outputted from the Teseo is just 12 nanoseconds. In addition, while the atomic clock includes a precision of 10-13 minutes, the Teseo-LIV3 comes with a precision of 10-9 minutes in a fraction of the price.

Utilizing A GNSS module also means having the ability to monitor time when protecting an program against environmental things. Throughout earthquakes or extreme circumstances, a real time clock might suffer with a float that could result in inaccuracies. A Teseo-LIV3 module is more resistant because the timing comes in a thing in space. Moreover, this type of remedy is indeed cost-advantageous that engineers frequently utilize multiple Teseo apparatus for redundancy purposes. Software engineers may also rely on sleeping manners to maintain the energy consumption. Designs which exude time maintaining do not require the embedded flash because they use external memory to capture information. Because of this, many select the Teseo-LIV3R as it features exactly the exact identical functionality because the Teseo-LIV3F for significantly much less.

Teseo Roadmap

GNSS modules have lots of applications that take advantage of their distinctive capacities. It clarifies why our teams will also be working on fresh Teseo versions to address upcoming issues . Engineers can thus anticipate modules with Increased efficacy (Teseo-LIV3) And precision (Teseo-LIV4), even if satellites are difficult to achieve, Thank you, for example, to detector fusion technology in dead-reckoning Calculations (Teseo-VIC3x) in automotive and industrial applications.
