Cellular service: SKMC is in a remote area, and also within the National Radio Quiet Zone surrounding the Green Bank Observatory. You should not expect your cell phone to have service. Other cell-based technologies like OnStar and cell-based navigation are also very unreliable. GPS and other satellite-based services are not affected and should operate normally.

FRS radios are encouraged for remaining in contact with your camping group, and for emergency notifications from the AHSP staff. Due to its low power, FRS at SKMC does not interfere with radio astronomy observations. FRS Channel 1 and 2 will be used for AHSP announcements and staff communications; as a courtesy to other attendees, please use channel 3 or higher for your camping group communications.

Wifi-based Internet service will be available at the Main Yurt so you can access the web, check your email, and upload photos. 

Phone service is available in the yurts and at the Earth Shelter. There is no charge for calls to destinations within the continental United States.
