Nowadays GNSS/RTK positioning is a very efficient technique for determination of coordinates especially when it is based on permanent reference stations. It allows every land surveyor to do his work easily and efficiently. However there are some situations when the use of RTK technique makes some difficulties, especially if the GNSS receiver has no full availability for satellites. It is well know that obstructions caused by tress, buildings, power lines etc., limit satellites availability. In those situations gross errors can appear. In order to avoid misleading coordinates occurring we can use more than one receiver has no full availability for satellites. It is well known that obstructions caused by tress, buildings, power lines etc. limit satellite availability. In Those situations gross errors can appear. In Order to avoid misleading coordinates occurring we can use more than one receiver. The paper presents practical tests and description of the GNSS/RTK technology based on the simultaneous use of three different GNSS receivers for the specific control points. Three different GNSS/RTK receivers can be placed on a special mounting beam and additionally RTK positions are send in real-time to a computer. The software on the computer analyses not only the precision but also the accuracy of determined RTK positions. In effects that solution can allow obtaining reliable coordinates even if observational GNSS conditions are very severe.
