Pajamas-940U GNSS receiver

► Product introduction

PJ The 1940U is a receiver with a high-precision module and a 4-star multi-frequency antenna. The receiver features high precision RTK positioning at the centimeter level, high antenna gain, miniaturization, high sensitivity, multi-system compatibility, and high reliability. It comes with a wireless data transmission module that allows GPS data to be transmitted wirelessly. It can effectively meet the needs of users.

1. The built-in wireless data transmission module (or called radio) has its own data transmission module antenna, which transmits GPS data through wireless transmission, and allows the other side to wirelessly transmit GPS data through wireless data transmission module. You can receive it.

2. Built-in high-precision RTK cm level positioning module, built-in GNSS 4-star multi-frequency antenna;

3. The multi-feed point design and perfectly symmetrical antenna structure are adopted, with a very stable phase center, reducing measurement errors in antenna pairs.

4. It has a clear effect on high gain, low standing wave ratio, low altitude signal reCEPtion, allowing stars to be received normally even in severe shielding.

5. Equipped with anti-multipath choke plates with anti-surge design, effectively suppress strong out-of-band interference signals, ensuring antenna reliability.

Designed with UV resistant PC material, it is beautiful and does not discolor the antenna casing even after long-term use outdoors. It has IP67 waterproof grade, high temperature resistance, sun protection and UV protection.

► application area

This receiver can receive GPS L1/L2 Glonus L1/L2 BDS B1/B2 GALILEO E1/e5b frequencies and supports RTK differential positioning to reach centimeter levels. To meet the needs of Current GNSS measuring devices for multi-system compatibility and high-precision users are widely used in the fields of geodesics, channel mapping, precision agriculture and marine surveying, and can also be selected and applied in military fields depending on application conditions. It can also be done..
