Let’s start a successful partnership with ESG!
Electronics Solution Group Ltd (ESG) offers a legacy series of GPS antennas designed for reliable satellite signal reception and accurate positioning for older-generation devices and systems. These antennas include active and passive GPS antennas, embedded modules, patch antennas, compact low-profile solutions, and external navigation antennas suitable for existing industrial, automotive, and commercial systems.
ESG legacy GPS antennas are engineered to provide stable performance, good sensitivity, and dependable signal reception even in standard operating environments. Available in various form factors, mounting options, connector types, and cable lengths, these antennas are intended mainly for maintenance, replacement, or service support of existing GPS-based systems.
Vehicle tracking and fleet management with legacy trackers
Telematics systems supporting 2G / 3G GPS connectivity
IoT and M2M devices based on older GPS modules
Navigation equipment for existing devices
Smart transportation systems with legacy GPS integration
Industrial automation systems with older GPS
Security and monitoring systems
Asset tracking using GPS-only technology
Embedded electronic devices with GPS modules
⚠️ Note: These GPS-only antennas are not recommended for new designs. For modern GNSS applications with multi-constellation support (GPS + GLONASS + Galileo + BeiDou), ESG recommends using the GNSS Antennas series.
Our engineering team can also support customized antenna solutions according to customer specifications and project requirements.
