Hagrid Hengtong Car Station AP-700

Key features:
Digital system: in line with PDT digital communication standards, high spectrum utilization, is 4 times the analog;Provide a rich and practical voice, data sMS and other services.
Clear voice
Using advanced digital voice codec and compression technology, anti-jamming is good, in the case of weak signal, still can maintain clear communication.
Soundcoder
AMBE or NVOC.
Real-time tracking
Built-in Beidou/GPS, not only can send native location information in real time, but also can be accurately located for emergency calls received, allowing users to have more security in the emergency.
Secure communications
Using digital codecation technology and modulation demodulation technology, the digitalization of voice transmission, analog, conventional machines can not be monitored, security is greatly improved.It also provides an encryption interface that supports end-to-end encryption cards, key management, and high-level security communications security requirements.
Chinese color screen
With the high-resolution TFT color screen on the big screen, the high-brightness display is friendly and convenient.
Digital compatible
With PDT digital cluster, digital routine, MPT analog cluster, analog conventional four modes of operation, to achieve a smooth transition from analog to digital communication, to protect the user's investment.
App extensions

Provides a dual-developed hardware/hardware interface for users and partners, with an optional 3G/4G module, to quickly meet the user's business upgrades and new business complements.
