Aether Magnetotelluric System
——Full-band natural source
geophysical electromagnetic system
Crystal Globe Geophysical Research
& Service, LLC is a geophysical company engaged in oil and gas exploration
and mineral survey, focusing on research and innovation of geophysical methods.
The company consists of a group of geophysicists, engineers and software
developers, most of whom have been in the oil and mineral industry for more
than 20 years and have extensive experience in borehole geophysical exploration
equipment design, high-precision data acquisition, intelligent noise rejection,
and weak signal data processing.
Aether is a new generation of
high-frequency and low-frequency simultaneous acquisition EM system with
synchronous timing and positioning via GPS, fully synchronized acquisition of
all channels and continuous time series storage. It can be used for any
traditional natural source EM method MT, AMT, and also for conventional active
method CSAMT, TEM, SIP, TDIP, etc.
Real-time transmission and
downloading of time series data through 3G/4G/5G network without on-site
downloading; suitable for long-period electromagnetic and seismic monitoring.
Ø Continuous time series storage
recording of multi-channel data to ensure data integrity, the most available
data in a limited period of time, improve field efficiency and increase the
means of anti-interference processing. Completely different from other
"old" instrument intermittent acquisition method, which destroys data
integrity, but also reduces the work efficiency.
equipment can only collect data once in a period of time in the high frequency
Aether Time interval
simultaneously collects low-frequency and high-frequency continuous time series
to ensure richer information and higher efficiency.
Ø Real-time impedance estimation
Real-time display of time series
waveform, spectrum, all operating states of the instrument, and real-time
processing and display of impedance.
Ø High and low frequency recording at the same
Support 24bit 6-channel high
frequency (up to 96kHz) and 32bit 6-channel low frequency (up to 4kHz) in
simultaneous acquisition and storage; simultaneous acquisition of high
frequency data and low frequency data from a single point, avoiding the problem
of splicing data collected by different instruments and at different times.
Ø Full-band acquisition
One set of system can solve the
problem of all frequency bands. Aether host has ultra-wide frequency band
range, one set of system can realize the full band acquisition of AMT, MT, LMT,
without replacing host or sensor.
Ø Universal electromagnetic channel
Aether series support sensor
inputs of any electromagnetic method, including electrodes, induction coil
magnetic probes, fluxgate probes, seismic velocity sensors, acceleration
Ø GPS synchronized time and coordinates
Accurate GPS timing ensures that
each sampling point is precisely timestamped and GPS position is recorded.
Ø Support GPS-free acquisition
In mountain or forest area where
GPS signal is unstable, the instrument's accurate internal clock still ensures
that each sampling point has an accurate timestamp after one GPS timing.
Ø Low power consumption design
Overall instrument power
consumption is less than 3w, only 1/5 of other similar instruments, reducing
the workload of field with batteries. Other similar instruments require 5 more
battery changes than Aether for the same data acquisition.
Ø High precision 32bit acquisition
32bit acquisition, only
5nv/sqrt(Hz), can be used for weak signal, low frequency long period signal
acquisition. The background noise is 1/20 of similar instruments.
of noise level between conventional instrument and Aether geomagnetic system
(conventional instrument:16 bit/24 bit ; Aether :24 bit/32 bit)
Ø Status indication
The instrument panel displays the
working status, GPS status, SD card storage status, and instrument operation
status; it is easy to determine the status and abnormal troubleshooting in the
Ø Large storage capacity
The instrument comes with a 32Gb
universal memory card, which can be expanded to 128Gb for easy data reading
Ø Fast data transfer back
SD data memory card supports
plugging and unplugging in any state, which is simple and convenient; it can
also be mapped to the network drive method for data download and deletion via
USB and network, without plugging and unplugging the SD card.
Ø Change card operation during acquisition
Support changing cards during
acquisition, which will not cause data loss or interruption; for continuous
long-period acquisition projects, the quality of stored data can be checked at
Ø One key acquisition, pre-stored parameter
One-click acquisition - parameter setting before the project starts,
no need to operate in the field.
Ø Support multiple interface connection and
real-time data transmission
Ethernet, WiFi connection, easy and convenient field operation.
Ø Upper computer for all status monitoring of
Support upper computer for all
instrument status monitoring to ensure field work quality and grounding
condition detection, including: battery status, GPS status, noise, offset,
ground resistance, SD card status, etc.
Ø Remote data transmission
Support network data back
transmission, or back transmission to a server.
Ø Instrument tandem networking
Support network tandem between
instruments, real-time data transmission. The transmission process does not
affect the local SD card storage.
Ø Industrial temperature
field applications and any environment.
Ø Support active and passive acquisition
System can be used for natural
source data acquisition, similar to MT/AMT/SP methods, or can be used for any
active electromagnetic method, such as CSAMT, TEM, SIP/IP, etc.
Ø Open data format interface
Open data interface is available.
Reading raw data, text output, and miniseed format output, etc., are supported
and it is easy for users to do researches and data analysis.
Ø Anti-harsh environment design
High stability and anti-seismic
design is friendly for field disturbance environment.
Ø Specially designed multi-parameter acquisition
Support multiple types of sensor
input, including: electrode, induction coil, fluxgate, speed sensor, and acceleration
