2.5 Layout design-in: Thermal management
During design-in, do not place the module near sources of heating or cooling. The receiver oscillator is
sensitive to sudden changes in ambient temperature which can adversely impact satellite signal
tracking.
Sources can include co-located power devices, cooling fans or thermal conduction via the
PCB.
Consider the following questions when designing in the module.
• Is the receiver placed away from heat sources?
• Is the receiver placed away from air-cooling sources?
• Is the receiver shielded by a cover/case to prevent the effects of air currents and rapid
environmental temperature changes?
⚠ High temperature drift and air vents can affect the GNSS performance. For best performance,
avoid high temperature drift and air vents near the module.
