Compliant to Project 25 (P25) standards, ASTRO® 25 site equipment is built to maximize channel up-time, simplify system technology refresh, optimize efficient site design and minimize the cost of ownership.
Easily add new features to your existing system with a simple software download. Based on an IP-architecture, ASTRO 25 G-Series equipment is designed so that many upgrades, migrations and conversions can be completed with only software installations.
Used in voting and simulcast networks, G-Series Comparators increase the talk-in coverage of a radio in the field. The comparators pick up audio from multiple sites and perform a frame-by-frame analysis to build a high-quality composite audio package for transmission. The GRV 8000 supports analog conventional and P25 digital conventional systems.
A space-efficient, single rack design, the GTR 8000 Expandable Site Subsystem (ESS) integrates up to six GTR 8000 Base Radios, redundant GCP 8000 Site Controllers or GPB 8000 Reference Distribution Modules, redundant Ethernet LAN switches, redundant network gateways, transmit combiners, and receiver multicouplers. This enables a highly resilient architecture that provides industry-leading protection against single points of failure at the RF sites while providing a turn-key site solution that minimizes site cabling connections and installation effort.
It supports ASTRO 25 simulcast and site repeater trunking operation, 3600 simulcast and intellirepeater trunking operation with SmartX, HPD, and P25 digital and analog conventional operation. When ordered as an ASTRO 25 Express System, the GTR 8000 Expandable Site Subsystem is the industry’s only turn-key, single-site Project 25 trunking solution.
GTR 8000 Expandable Site Subsystem
Protected from the elements, the G-Series Compact Site is a complete ASTRO® 25 site that can house up to three GTR 8000 Base Radios in an outdoor, environmentally controlled cabinet. It is ideal for Project 25 (P25) deployments where building enclosures are not cost-effective or feasible due to difficult terrain.
The GCP 8000 Site Controller is used at an ASTRO 25 trunking site to assign voice and data channels, manage and report alarms on site resources, provide Ethernet switching capability, and provide a frequency reference to GTR 8000 Base Radios. The frequency reference is provided either via a GPS receiver or an ultra high stability oscillator. The nature of these frequency references eliminates or minimizes site visits for frequency tuning servicing.
Designed to support ASTRO 25 trunking simulcast, 3600 trunking simulcast with SmartX, HPD, and P25 and analog conventional operation, GTR 8000 Base Radios offer additional design flexibility for infrastructure sites where equipment may have to be interchanged individually during a technology refresh or when used as a station replacement for QUANTAR™ or STR 3000 stations.

In conventional and trunking voting or simulcast voting applications, the GPW 8000 Receiver increases in-bound signal coverage for subscribers. Physical space is optimized at receive-only sites with the GPW 8000 space efficient dual receive module design.
Used in voting and simulcast networks, G-Series Comparators increase the talk-in coverage of a radio in the field. The comparators pick up audio from multiple sites and perform a frame-by-frame analysis to build a high-quality composite audio package for transmission. The GCM 8000 supports P25 digital conventional and P25 trunking systems.
Gradually migrate analog simulcast and voting systems to IP-based transport.
