Track-while-scan ( TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range search (LRS), air ...
Project 25 ( P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. [1] P25 radios are a direct replacement for analog UHF (typically ...
A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a talkgroup) with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time ...
Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.
Android Team Awareness Kit ( ATAK) is an Android smartphone geospatial infrastructure and military situation awareness app. It allows for precision targeting, surrounding land formation intelligence, situational awareness, navigation, and data sharing. This Android app is a part of the larger TAK family of products. [1]
A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It's usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images.

The Domain Awareness System is the largest digital surveillance system in the world [2] as part of the Lower Manhattan Security Initiative in partnership between the New York Police Department and Microsoft to monitor New York City. [3] It allows the NYPD to track surveillance targets and gain detailed information about them, and is overseen by ...
A third type of context to share to improve or enhance situational awareness is the user's audio. In the Thunderwire system, researchers developed an audio-only media space that allowed friends to share raw audio from their mobile devices' microphones. This system, which in essence was a perpetual conference-call, allowed users to listen to ...
