SPACE INSTRUMENTATION / MoMerV
We are developing MoMerV to measure the atmosphere that shapes satellite orbits. NexAI brings mission operations experience, an eight person team and agreed access to Florida Tech facilities to the work.

SPACE INSTRUMENTATIONMEET
At orbital speed, even a thin atmosphere matters. MoMerV is designed to measure the momentum of incoming neutral gas, then combine that measurement with gas composition to estimate thermospheric density.
Three angled silicon force plates and their shielded reference twins form the sensing core. A rotating chopper separates the flow signal from slow drift. A miniature time of flight analyser supplies the composition measurement.

Science plates and shielded twins separate the flow response from shared disturbances. The three plate angles constrain the calibrated surface response.

MOMERV / DEVELOPMENT & MANUFACTURING
Making one instrument is the first step. Our production plan ties each part, assembly and measurement to a controlled record, so the next unit can be built and checked against the same requirements.
WHAT THE INSTRUMENT MEASURES
The force channel measures momentum transfer. Composition and surface response enter the retrieval model; orbital velocity and pointing come from the host. The result is a density estimate with uncertainty and quality flags.
The baseline is the calibrated thermal neutral mixture. Hot neutral oxygen needs a separately validated response correction.
Ion rejection grids suppress the charged particle contribution before the neutral flow reaches the sensing surfaces.
THE BUILD PATH / FOUR ENGINEERING GATES
DESIGN RELEASE
Freeze the die geometry, electrode gap, plate angles and chopper clearances together. Review the harness route, fastener access and mounting loads before releasing the parts.
FABRICATION & ASSEMBLY
Screen sensing dies for capacitance, resonance and pull in behavior. Machine the housing and fixtures, inspect critical dimensions, then assemble the force channels, rotor and analyser.
CALIBRATION & VALIDATION
Apply known electrostatic forces, then compare thermal beam measurements with an independent reference. Freeze the fitted coefficients before testing withheld conditions.
QUALIFICATION & REPEAT BUILD
Compare functional and calibration results before and after vibration and thermal vacuum exposure. Tailor the test levels to the host and close discrepancies before flight acceptance.
ENGINEERING REFERENCES
Our development plan links each requirement to an analysis, inspection or test. These references guide the planned work; qualification levels and acceptance criteria will be agreed with the flight provider.

THE PEOPLE BEHIND THE WORK
AN INDEPENDENT AMERICAN COMPANYNexAI is led by Ivan Lavlinski, whose background includes ground systems engineering for NOAA’s GOES program and flight operations work on TRMM. That experience informs how we design, review and test our systems.
LEADERSHIP
Chief Executive Officer · Principal Investigator
Ivan is CEO of NexAI INC, an American company with eight employees. He leads technical direction, research and development planning. From 2017 to January 2025, he supported ground systems and flight operations for NOAA’s GOES R series. Earlier work included TRMM flight operations at NASA Goddard.
He holds a bachelor’s degree in Astronautical Engineering from Capitol College and master’s degrees in Space Systems (2015) and Commercial Space Enterprise (2017) from Florida Institute of Technology.
At NexAI, he leads an eight person team and coordinates the company’s engineering projects and university collaboration.
