DRT1000 System Software

DESCRIPTION
The DRT1000 System Software is a suite of applications that includes the software that runs on the DRT
system, Alaska (GUI), Applause (Audio Playback), DF and Geolocation (with DRTview), and Yukon (IP
Configuration utility). The DRT1000 system may be used to: identify and collect audio, data and Signal
Related Information (SRI).
The DRT1000 unit software runs on the DRT1000 family of SDR receivers, transmitters and transceivers.
The unit hardware and the format “keys” define which software features are active, including options such
as DF.
DRT units are controlled via a connected computer loaded with the DRT1000 GUI applications.

Controller PC System Requirements: DRT GUI software runs under the Windows XP or
Windows 7 operating system.

Approved by DoD/OSR for public release under 14-S-2412 on 28 August 2014. Data, including specifications,
contained within this document are summary in nature and subject to change without notice.

Features
Integrated Spectrum Analysis
Tool
The Spectral Display Unit (SDU) provides a
graphic display of detected radio-wave
activity. User-defined parameters such as
frequency range, threshold, etc. control the
display. More than one spectral display
can be monitored simultaneously. Spectral
displays may be recorded and played back
for post-collection analysis.

Configuration Wizard
Alaska is the primary GUI used to configure
the DRT system and monitor the mission.
Within Alaska, the Configuration Wizard
facilitates setup of a unit. This mode steps
through a complete mission configuration
for all formats, automatically assigning
receivers and tuners in response to user
input.
For some services a web interface may be
used in addition to Alaska.

Audio Playback and Transcription
Applause, DRT’s playback and transcription tool, is the default audio playback tool (any audio playback
utility can be set as the default playback tool). Applause can playback and compress digitally recorded audio,
bookmark audio sections, display SRI data, and provide a means to create audio transcriptions.
Streaming Data Service (SDS)
SDS can stream timestamped audio and I/Q data to a connected server.

Direction Finding and Geolocation
(Optional)
Using state-of-the-art algorithms, the DF software
module (running on the DRT receiver) controls
the DF antenna and computes line-of-bearing
(LOB) results continuously or on demand.
Alaska, the DF control software, provides
integrated direction finding control and reporting.
DRTview, the DRT geolocation tool, provides
LOB display and map overlay.
Using the
integrated GPS antenna, DRTview can estimate
the target’s latitude/longitude and display fix
ellipses.
DRTview accepts LOB input from
multiple DRT receivers on a network and/or logs.

GPS Integration and External Time Synchronization
The DRT1000 Software integrates DRT unit location information
provided by GPS receivers. The GPS receiver may be external
or internal. Collected GPS information can be saved to the logs
and exported. The DRT system’s clock can be synchronized to
GPS time. Additionally, the system supports:


Optional 10 MHz/1PPS synchronization to external sources.



Optional synchronization to external timing sources.



Time and frequency disciplining and timestamping of
collected raw and demodulated data using internal GPS or
externally supplied reference.

IP Configuration
DRT’s software utility Yukon provides IP configuration capability
for DRT1000 units. DRT1000 systems support both static and
dynamic (DHCP) IP addresses.

Network Time Protocol
The DRT1000 Software package includes Domain Time II, a
COTS network time protocol program to synchronize the DRT
system’s time with an NTP server.
