1. A sensor package, comprising:
a sensor housing unit;
a first accelerometer sensor configured to acquire a first set of measurements associated with a ground roll of seismic energy detected within a first measurement range of the first accelerometer sensor, the first accelerometer sensor having a first accuracy property, a first resolution, and a first calibration stability associated with an amount of time; and
a second accelerometer sensor configured to acquire a second set of measurements associated with the ground roll within a second measurement range of the second accelerometer sensor, wherein the second measurement range includes a higher measurement value as compared to a greatest measurement value within the first measurement range, the second accelerometer sensor being a different type of accelerometer sensor as compared to the first accelerometer sensor and having:
a second accuracy property greater than the first accuracy property,
a second resolution lower than the first resolution; and
a second calibration stability greater than the first calibration stability, wherein the first measurement range and the second measurement range comprise an overlapping range used to automatically calibrate the first set of measurements at a periodic frequency, wherein the first set of measurements is automatically calibrated with respect to the second set of measurements based on a first portion of the first set of measurements and a second portion of the second set of measurements, wherein the first portion and the second portion are within the overlapping range; and
a processing system configured to obtain a third set of measurements having a third resolution higher than the second resolution by applying a gain to the second set of measurements based on automatically calibrating the first set of measurements, wherein the third set of measurements is within the first measurement range and corresponds to a saturation region of the first accelerometer sensor.
