VNet8 GNSS CORS Receiver.
The infrastructure behind every RTK fix. A 1408-channel reference receiver with 64 GB storage, 15-hour backup battery, unlimited correction streams, and IP68 MIL-STD-810G protection — purpose-built for permanent CORS and VRS deployments.
The VNet8 doesn't survey — it makes surveying possible. Deploy it as a permanent reference station and serve unlimited RTK rovers within a 20–50 km radius. 64 GB internal storage logs months of data. A 12500 mAh backup battery keeps streaming through utility outages. Embedded OS firewall and encrypted communications protect your data. And web-based remote management means you never need a site visit to check status or push an update.

Reference Infrastructure
One receiver. Unlimited rovers.
Deploy a VNet8 with a choke-ring or geodetic antenna at a known point, and every RTK rover within 20–50 km receives centimeter-accurate correction data — simultaneously. The receiver handles all the complexity: NTRIP protocol serving, dual-format RINEX data logging, satellite health monitoring, and automatic switchover to backup battery during power outages.
For network operators, the VNet8 is designed as a node in distributed CORS/VRS architectures. Embedded OS firewall, encrypted communication, and web-based remote management let you operate regional networks without visiting individual sites. Pair with Hi-Target's network software for full VRS/FKP/MAC generation.

Key Features
Six engineering decisions for permanent deployment.
FEATURE 01
1408-Channel Multi-Constellation Engine.
Tracks GPS (L1/L2/L5), BDS (B1I/B2I/B3I/B1C/B2a/B2b), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b/E6), QZSS (L1/L2/L5/L6), NavIC (L5), and SBAS (L1). The same receiver engine used in Hi-Target's iRTK5 and V700S rovers — ensuring complete signal compatibility across your entire fleet. Total-star constellation VRS technology and high-precision error correction support longer baselines and reliable correction data.

All operational GNSS systems tracked simultaneously
FEATURE 02
Embedded OS Firewall
Encrypted communication and embedded firewall protect data privacy and security. Critical for government CORS networks and commercial VRS operators handling sensitive positioning data.
FEATURE 03
Web-Based Remote Management
Configure, monitor, download data, and push firmware updates via Ethernet or WiFi — no physical site visit required. Manage your entire CORS network from a single browser.
FEATURE 04
15h+ Backup Battery
12500mAh internal lithium keeps the station operating through utility outages. 7-36V DC input compatible with solar panels and UPS for fully autonomous remote installations.
FEATURE 05
Massive I/O — Every Interface
3× RS232, 2× USB, RS485, RJ-45 Ethernet, WiFi 802.11b/g/n, 2× SMA (PPS + 4G modem), 2× TNC antenna ports. Connects to everything in your CORS infrastructure.
FEATURE 06
Designed for distributed CORS networks.
The VNet8 isn't a rover repurposed as a base — it's engineered from the ground up as a network node. High-speed micro CPU, 64GB internal storage with TF/USB expansion, dual-format GNS+RINEX logging, unlimited NTRIP streams, and 50Hz raw data rate make it suitable for both single-station CORS deployments and multi-station regional VRS networks serving hundreds of concurrent users. Pair with Hi-Target's network management software for centralized control.

Frequently Asked
Common questions about the VNet8.
What is the VNet8 GNSS CORS receiver?
+
The VNet8 is Hi-Target's purpose-built 1408-channel GNSS reference receiver for CORS and VRS networks. 64GB storage, 12500mAh backup battery (15+ hours), IP68 MIL-STD-810G, Ethernet + WiFi + 4G, unlimited NTRIP correction streams, embedded OS firewall, and web-based remote management.
How many rovers can the VNet8 support?
+
Unlimited. The Ethernet interface supports unlimited concurrent NTRIP correction streams and data logging threads. A single VNet8 with a choke-ring antenna can serve dozens to hundreds of RTK rovers simultaneously within a 20-50km radius.
What happens during a power outage?
+
The internal 12500mAh battery automatically takes over, providing 15+ hours of continuous operation — data logging and correction streaming continue uninterrupted. The 7-36V DC input is compatible with solar panels and UPS systems for fully autonomous remote installations.
Can the VNet8 be managed remotely?
+
Yes. Web-client management via Ethernet or WiFi. Configure settings, monitor satellite health, download data, and push firmware updates from any browser. The embedded OS includes firewall and encrypted communication for security. Also supports cellular (4G/LTE/GSM) for sites without wired Internet.
Which antenna should I pair with the VNet8?
+
For permanent CORS: AT-45101CP 3D choke ring antenna (≤±1mm phase center, IGS/NGS certified). For mobile/semi-permanent base: AT-35101H geodetic antenna (460g, ≤±1.8mm phase center). Both available from Sicher 3D as bundles with the VNet8.
