We tried out Gezgin-1, a portable GNSS receiver designed and manufactured in Türkiye by ELYA Teknoloji San. ve Tic. A.Ş., with Kocaman Pro. From the start, we have coded Kocaman Pro with advanced academic formulations running in the background to produce the most precise and accurate results. We are happy to share the unique experience we had in the field with Kocaman Pro and the real-time coordinates delivered by the Gezgin-1 GNSS receiver connected to TUSAGA-Aktif (CORS-TR).
What Is Gezgin-1 GNSS?
The Gezgin-1 GNSS receiver was designed and manufactured in Türkiye by ELYA Teknoloji San. ve Tic. A.Ş. It is ergonomic, reliable and affordable for anyone who needs precise positions and coordinates in the field, and it works with all your mobile devices: smartphones, tablets and laptops.
Connected to TUSAGA-Aktif (CORS-TR), it delivers a positional accuracy of ±2 cm in real time. With SBAS satellites, sub-meter accuracy is at your fingertips. (For details, visit www.gezgingnss.com.)
Our Gezgin-1 GNSS Experience with Kocaman Pro
First, after establishing a Bluetooth connection between the Gezgin-1 GNSS receiver and an Android mobile device, we used third-party middleware to receive TUSAGA-Aktif (CORS-TR) real-time corrections and increase positional accuracy. Through this middleware, Kocaman Pro accessed the position data obtained with Gezgin-1 and refined with TUSAGA-Aktif (CORS-TR), using the mock location (mock GPS) feature of Android devices.
We then carried out detailing, stakeout and area measurement in the field with Kocaman Pro and evaluated the results with mobility in mind. As expected, the results improved markedly.
We also made the raw data from Gezgin-1 GNSS available to Kocaman Pro directly, without the middleware, again through the mock location (mock GPS) feature, and carried out detailing, stakeout and area measurement in the field. In this case, the values we obtained were sometimes at centimeter and sometimes at decimeter level of accuracy.
You can also use Gezgin GNSS, the mobile app that ELYA Teknoloji provides with Gezgin-1. It connects directly to the receiver and to CORS-TR, so you can carry out professional surveys with centimeter accuracy in open terrain.
In conclusion, bringing this locally produced hardware and software together delivers an ergonomic, reliable and affordable solution for users who need precise positions and coordinates in the field. We also identified the steps needed for Kocaman Pro to work directly with GNSS receivers that can receive RTK corrections, such as Gezgin-1 GNSS.
