The GDL radio systems are high speed wireless UHF radios intended for RTK connection between a single GPS base station and one or more rovers in field.

Mechanically GDL are really robust, waterproof and dustproof. Electrically they provide a long working time without needs of battery recharge.

GDL radios represent the entry level of UHF radio proposed by Stonex for Base-Rover GPS systems.

GDL radios are available in three different models:

• GDL 2 (0.5 W - 2 W)
• GDL 5 (2W - 5 W)
• GDL 20 (10 W - 25 W)

GDL features at a glance

• GMSK digital modulation
• Transparent proprietary protocol for data transfer
• Advanced wireless booting technology, data processing technology and base band processing technology guarantee low value of Bit Error Rate
• Baud-rate: 9,600 (GDL-2 GDL-5) or 19,200 bps (GDL-20)
• 4 (GDL2-GDL5) or 8 (GDL20) radio channels in the range 450-470 MHz, whose frequencies are selectable also by PC software
• Different format supported for RTK correction: CMR, CMR+, RTCM 2.3, RTCM 3
• The Stonex S9 GNSS rover will set automatically to the correct correction format
• The radios use a 5-pin LEMO for getting data from the base, so it can work with any equipment having a 5 pin LEMO connector
• The basic model GDL 2 has 0.5 W - 2 W emitting power, for countries where laws authorize there are also available GDL 5 (2W - 5 W) and GDL-20 (10 W - 25 W)
• Waterproof and dustproof for a long life also in hard environment condition

The equipment has 2 years of warranty starting from data of first sale. Contact authorized Stonex Dealers for purchasing.
