CHCNav GNSS RTK Receivers
CHCNav builds professional quality, high-precision RTK GNSS
receivers with USA ready field software options suitable for survey
and engineering use. The CHCNav receivers have best-in-class under
canopy performance, long battery life, precise tilt-compensation and
long range UHF radios.
iGage bundles these receivers with bright and fast field ready
tablets.
Current CHCNav GNSS device offerings are:
i83 for non-visual applications
i89 for visual survey applications
iBase for Base applications
i83 + iGR 35-watt radio
for UHF Base applications
These receivers are compatible with
multiple field software solutions.
We strongly recommend LandStar8 or
X-PAD running on
Android data collectors.
Each of these receivers includes a
Wi-Fi NTRIP Caster for streaming RTCM3.x corrections to RTK
UAV's. Built-in
APIS service allows Base-Rover via CGNAT cellular connections
with no additional subscription or charge.
The iGage
iGx-Download tool simplifies submission of observation files to
NGS OPUS and exporting high-rate static data.
Discounted packages are available when you bundle LandStar8 or X-PAD
with our flagship Tripletek 9 Pro
rugged tablet.

Tracking: All of these devices utilize the
UM980 GNSS engine with full 1408-channel GNSS tracking taking advantage of GPS, GLONASS, Galileo and BeiDou (including BeiDou3)
providing robust data quality and unequaled under canopy performance
and short time-to-fix in the most challenging environments:
GPS L1C, A, L2P(Y), L2C, L5;
GLONASS L1,L2;
Galileo E1, E5a, E5b, E6;
BeiDou B1I, B2I, B3I, B1C, B2a, B2b;
QZSS L1, L2, L5, L6; PPP B2b-PPP; SBAS L1, L5
IMU: These devices all include an integrated
IMU-GNSS with fast 3-second initialization and 200Hz updates delivering
3cm accuracy up to a 30-degree pole tilt.
Field Software: detailed
comparison
LandStar8: All devices are fully compatible
as native instruments with
LandStar8 field software. LandStar8 is the preferred solution
for new users and deployments and required for Visual Survey
applications.
X-PAD: All devices are supported by
X-PAD, however
the visual stakeout and visual survey capabilities of the i89
and i93 are not supported.
Field Genius: All devices are compatible
with Field Genius Android. Manual entry of antenna parameters
may be necessary.
SurvXX: All devices are nominally compatible
with SurvCE / SurvPC Version 6.04-6.08 with some [
caveats ].
External Radio: The i83, i93 and iBase have
standard 7-pin LEMO (9-28 VDC power + RS-232) ports for connection
to an external radio and power source. External power does not charge
the internal batteries. All these devices support the CHC516 compressed
correction format to extend Base run time.
External Power and Charging: The i73+, i83,
i89, i93 have internal batteries which are charged by a Type-C cable.
The iBASE batteries are charged in an included external 4-slot charger.
Network Cell Modem: The
i83, i93 and iBASE have
Quectel EG25-G LTE 4G modems with support for:
LTE-FDD: B1/B2/B3/B4/B5/B7/B8/B12/B13/B18/B19/B20/B25/B26/B28

The i93's video photogrammetry
technology enables accurate visual surveys, simplifying
point measurements without the need for complex
offset methods and making it possible to survey
previously hard-to-reach, signal-obstructed, and
hazardous locations.
The i93 can also be used to complement aerial
surveys generated from oblique imagery since its
data is compatible with the most popular 3D modeling
software.
