GPS reception
GPS reception is highly dependent on atmospheric conditions.
Reception problems can occur in the following situations:
• GPS signals are blocked within tunnels.
• Covers suppress the GPS reception signal.
• GPS signals are blocked within buildings.
• In side buildings (high-rise buildings in particular), the GPS signal is lower and interference
can occur.
• In forests or when passing through densely vegetated areas, the GPS signal can be lower
and interference can occur.
The following factors can also impair signal quality or interfere with the reception signal:
• Sun blinds inside a vehicle
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass
• Proximity to metallic & conductive objects
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-control-
led headphones, radio-controlled speakers, radio-controlled weather stations, baby phones
etc.)
• Proximity to electric motors, transformers, power supply units
• proximity to badly shielded or openly operated computers or other electric devices.
