FCC RULES AND REGULATIONS

Licensing Requirements

It is the responsibility of the PDL Base station owner to comply with applicable rules and regulations

concerning the operation of a radio transmitter. In the United States, the FCC regulates the licensing of

this equipment.

Application for a license is made by submitting FCC form 600 along with evidence of frequency

coordination (if required) and applicable fees. Similar licensing requirements exist worldwide. Penalties

for broadcasting without a license can be severe, and may include the confiscation of your radio and GPS

equipment.

For more information, contact our customer service department.

 Warning: Always obey local licensing requirements and restrictions.

Equipment Compliances

PDL products have been tested and found to comply with Parts 15 and 90 of Title 47 of the Code of

Federal Regulations. The PDL products have also been tested and found compliant for type certification

and approval in many other countries worldwide.

For more information concerning our worldwide compliances, contact our customer service department.

Being Part of the RF community

Operation of a licensed radio product makes you a member of the RF community. Be aware that virtually

all frequencies licensed are provided on a shared basis with other users. Each frequency used in RTK

GPS activities has certain restrictions and limitations. For complete information, refer to Part 90, Title 47,

of the Code of Federal Regulations.

Most frequencies sharing data transmissions and voice transmissions give priority to voice users. Be

mindful of the persistent nature of a GPS RTK data transmission and always limit your RF transmission

output power when performing close-in survey situations to avoid interference with co-channel users. We

recommend using the low RF power setting for construction site and other line-of-site surveys with

baselines less than 2 miles (depending on terrain).

 Warning: If you are in conflict with a co-channel user, select another frequency to avoid formal

FCC actions. In most cases you are required to vacate a frequency upon complaint by a shared channel

voice user.

Most survey operations are itinerant in that the system is moved on a frequent basis. For fixed system

installations, you should not use frequencies set aside for itinerant operations, but should coordinate a

frequency based on the fixed area operation.

Regulations differ from country to country, so please be aware of the local regulations prior to using the

PDL equipment.

Automatic Station Identification

For operation in the United States, the FCC requires that radio transmitters used for GPS RTK

applications periodically broadcast a station identifier. The station identifier is the call sign assigned to

you on the station license.

The PDL supports the broadcast of station identification in a manner that meets the requirements of the

FCC. Upon receipt of equipment, program your FCC callsign into the configuration of your PDL using

PDLCONF software. This is only required for transmitters.
