Visitor’s Guide

APL is located midway between Washington and Baltimore, with convenient access to major highways and local attractions. The Laboratory is a secure facility, operating under Department of Defense regulations for restricted entry. All visits to the Laboratory must be preapproved via written request and notification by responsible staff members. Staff members hosting visitors are responsible for ensuring that all security requirements are met.

Entry/ID Requirements: Visitors must present photo identification to the lobby receptionists, sign the visitor register, receive the appropriate badge, and remain under escort unless otherwise authorized by Visitor Control. Passports are required for foreign visitors, and resident aliens must present their Resident Alien Card (green card) for entry to the Laboratory. Questions regarding the status of a visitor's access to the Laboratory should be directed to Visitor Control (Phone: 240-228-5661 or 443-778-5661; Fax: 240-228-6400 or 443-778-6400). Visitors attending a meeting should have their visit request faxed to Visitor Control or sent via SMO code 888984.

Restricted/Controlled Items: Visitors should be aware of APL rules for bringing restricted and controlled items, such as electronic devices, on site.

Parking: Visitors should park in the designated visitor parking lot closest to the building where the meeting is being held (see APL Campus Map) unless directed elsewhere by their APL point of contact. When leaving the Laboratory, visitors should ask the Security Officer or Lobby Receptionist for the appropriate gate combination to exit the parking lot.

Wireless Coverage: APL has a Guest wireless network that is available for general use by visitors to the APL campus. This network provides Internet access, can be used to send encrypted communications, and supports 802.11 b/g/n. Access to the network requires a Wired Equivalent Privacy (WEP) key and a Guest user password. Visitors will need to set up a "guest" network name or Service Set Identifier (SSID) through their wireless configuration utility using the WEP key.
