MEASUREMENT RESULTS IN COMPLIANCE WITH REGULATIONS

Ensuring the accuracy and quality of documentation is an elementary success factor for NAVA. In Germany, the accuracy requirements for the documentation of electricity, gas and water networks are defined by the regulations (VDE-AR-N-4201 and DVGW GW 120). NAVA fulfills these accuracy requirements with the mobile devices approved according to the NAVA whitelist. With this set of rules for network documentation in utility companies updated in December 2021, NAVA can be used as a photogrammetric method – and thus also in accordance with GW 128 (A) (as of 11/2024) and VDE-AR-N 4204 (as of 06/2024); the technical specialist makes the specifications for this. All other minimum requirements of VDE-AR-N-4201 and DVGW GW 120 are also fulfilled.

NAVA TEST FIELD

To be able to test the app again and again on the latest smartphone models, we use our own flexible test track with a real pipe network. This simulates a house connection trench, which is used to collect comparative data and to ensure the precision of the measurements. With the test field, we are able to thoroughly check the devices used and thus ensure the accuracy of the technology.

CHECKED SMARTPHONES ARE ON OUR HARDWARE WHITELIST

=
On our test field, a trained geomatics technician checks current smartphone models (iOS/Android systems) for accuracy and function.
=
In particular, the iPhone Pro editions with their Lidar sensor and the Google Pixel Pro series have a camera optimized for augmented reality.

ACCURACY IS ALSO A MATTER OF THE USER

TEST MODE AND QUALITY INDICATOR

=
The integrated quality indicator (QI) gives the user direct feedback on the quality of the measured points.
=
In addition, NAVA switches to the so-called test mode after each measurement. This is used to check the set points and offers the possibility of making corrections.

ASSISTANCE BY ASSISTANTS

=
The NAVA assistant does not leave the user alone but provides continuous assistance during the measurement process to ensure the best measurement results.
=
All users also receive training videos, a guide to measurement and, at the beginning, detailed training with plenty of tips for handling.
=
Individual training videos, adapted to your company, are available directly in the APP.
