Bad Elf's line of GNSS receivers empower GIS and survey professionals to collect high-accuracy field data using any phone, tablet, or laptop. Our products work with any location-based app running on iOS, Android, and Windows. All Bad Elf’s Bluetooth receivers have an integrated LCD screen and intuitive user interface to provide status information and perform standalone data collection when needed. Our flagship Bad Elf Flex GNSS receiver is the first survey-grade receiver to support a flexible "pay only for the accuracy you need" daily token model that minimizes up-front costs and eliminates monthly subscriptions. Now your entire team can collect high-accuracy data when needed while staying within your budget. When the iPad debuted over a decade ago, Bad Elf was one of the first GPS accessory manufacturers to provide rock-solid GPS reception for moving-map aviation apps used by private, commercial, and military pilots. Over the years we started working with more GIS and survey customers. Their feedback and requirements have driven our team to build the most powerful GNSS receivers that are also affordable, accurate, and intuitive.
