Dear Trak4 competitor, 

We are proud to announce the release of version 2 of Technical Annex of Track4 - Foot-mounted IMU ! 

If you are interested in dead-reckoning with accelerometer, gyroscope and magnetometer sensors coupled with GNSS data and barometer, then this track is for YOU ! 
In this v2 you will be able to get access to the testing trail (with ground truth) specifically recorded in Tampere (Finland). It is the perfect opportunity to tune your algorithm to be fully ready for the O NLINE competition that will be hosted between the 8th and 10th of September 2025 . 

In the mean while, do not hesitate to contact us (Ni and myself) if you have any questions ! 

As reminded in the email below :

* * * CALL FOR COMPETITION 2025 * * * 

Twelfth IPIN Competition 
onsite and offsite Indoor Localization 
[ https://competition.ipin-conference.org/ | https://competition.ipin-conference.org ] 

offsite: 8-10 Sep, EvaalAPI web service 
onsite: 13-14 Sep (tentative), Tampere (FI) 
awards: 18 Sep, IPIN conference 

================================================================================ 

The International conference on Indoor Positioning and Indoor Localization 
(IPIN) is pleased to announce the twelfth IPIN Indoor Localization Competition. 
The competition is aimed at bringing together the academic and industrial 
research communities for evaluating different approaches and envisioning new 
methods for indoor and seamless localisation, an area where no generally 
accepted standards exist yet. 

The competition builds on the experience of previous competitions and is based 
on the EvAAL framework, ensuring experience, solidity and a well-founded 
scientific method. The IPIN 2025 Indoor Localization Competition consists of 
several Tracks: 

• Track 1: Smartphone (onsite) 
• Track 3: Smartphone (offsite-online) 
• Track 4: Foot-mounted IMU (offsite-online) 
• Track 5: Smartphone with navigation robot (offsite-online) 
• Track 6: Smartphone on vehicle (offsite with onsite survey) 
• Track 7: 5G CIR + IMU (offsite-offline) 

Results will be presented during dedicated sessions of the IPIN conference, 
during which prizes will be awarded to the winners. 


ONSITE TRACK 

The onsite competition will take place in Tampere, before the IPIN 
conference. An actor carries the competing system by walking in the competition 
area. Competing systems process data locally, without using any external aid, 
and provide position estimates in real time. Survey of the area and system 
calibration is restricted to a single day, before the competition proper. 

Track 1 – Smartphone: The actor walks carrying a smartphone which runs the 
competing system, using the sensors available on the smartphones to identify the 
user's position. 


OFFSITE TRACKS 

Competitors in offsite competitions are provided with sensors data and use them 
to estimate the user position. Competitors calibrate their algorithms in 
advance using ground truth reference data (testing trials) and compete using new 
unreferenced data (scoring trials). Scoring trials are run on a Track-specific 
day. 

Once testing trials are published, competitors can run them at their premises. 
When the EvaalAPI server is made available, they must run the testing trials on 
it. Scoring trials are provided to competitors only once they complete a run of 
the testing trials. 


OFFSITE-ONLINE TRACKS 

Competitors run their trials through the EvaalAPI in online mode to emulate the 
causal, real-time behaviour of onsite Tracks. See the paper "Offsite evaluation 
of localization systems: criteria, systems and results from IPIN 2021-22 
competitions" for a conceptual overview. 

Track 3 – Smartphone: A pedestrian walking under realistic conditions in 
buildings with possibly small outdoor parts, using data provided by a 
conventional smartphone. 

Track 4 – Foot-mounted IMU: A pedestrian carries ULISS (Ubiquituous Localization 
with Inertial Sensors and Satellites) on his foot while walking a path with 
possible small outdoor parts. ULISS provides IMU, magnetic and pressure 
readings plus GNSS data. No maps are provided. 

Track 5 – Smartphone with Navigation Robot: A pedestrian in a museum records PDR 
and VIO data provided by a conventional smartphone. A navigation robot moves 
with/around the pedestrian and provides its location and UWB ranging/AoA between 
the smartphone. 


OFFSITE-OFFLINE TRACK 

Competitors run their Trials through the EvaalAPI in offline mode, where 
competitors download sensors data all at once and have a limited time to upload 
all estimates at once. 

Track 7 – 5G CIR + IMU: A pedestrian with a smartphone moves through a 
warehouse-like environment in LOS and NLOS conditions and observes Channel 
Impulse Response and IMU data. 


TECHNICAL COMPETITION DETAILS 

The evaluation criteria for the competition, restrictions on the accepted 
technologies, technical rules and a description of the benchmarks are detailed 
in the technical annexes to this call. Possible refinements of the annexes, 
even based on applicants' comments, will be distributed on the competition 
discussion mailing list contest at evaal.aaloa.org and will appear on the 
competitions site [ https://competition.ipin-conference.org/ | https://competition.ipin-conference.org ] . 

Competitors in offsite Tracks obtain sensor readings and submit position 
estimates through the EvaalAPI web service [ https://evaal.aaloa.org/evaalapi | https://evaal.aaloa.org/evaalapi ] . 
The aim is to emulate a causal process similar to the data flow of an onsite 
Track: input data can be read only once and only in sequence, and the timestamp 
of each submitted position estimate is the same as the latest sensor reading. 

All the data gathered by the competition committee during the competition, 
including data produced by competing systems in offsite Tracks, will be 
published after the competition for the purpose of research and comparison. 
Winners of the competition are announced on the IPIN web site and on the contest 
mailing list. 


COMPETITOR ADMISSION PROCESS 

A competitor can be any individual or group of individuals working as a single 
team, associated to a single or a number of organizations, who wants to 
participate in one or several tracks. Only one team from the same organisation 
(laboratory) is allowed to compete. 

Competitors apply for admission to the competition tracks at 
[ https://competition.ipin-conference.org/current-competition/application | https://competition.ipin-conference.org/current-competition/application ] by 
providing a short (2 pages in PDF) technical description of their localization 
system, including a description of the algorithms and protocols used. Track 
chairs will accept or refuse the application in a short time, based on technical 
feasibility and logistic constraints. 

After acceptance of the competitor's technical description, one member of the 
competing team is required to register on the IPIN conference site, specifying 
the Track to which the registration is linked. Full registration to the 
conference covers participation in the competition process for one Track 
(allotted time, support and space) and the submission of one paper describing 
the system. Participation in additional Tracks can be added for an additional 
fee. A reduced registration fee not including access to the conference is 
available for offsite Tracks. 

Competitors who wish to test their onsite system which does not fit any of the 
onsite tracks may ask chairs of Track 1 to be admitted off-track, which will be 
granted subject to organisational contraints.
