"The South Texas heat caused screens on our previous handheld devices to become unresponsive, whereas Bad Elf equipment functions reliably in that environment. We choose a GNSS partner that supports the way our teams actually work, in real-time"
— Ruben Cano
GIS Manager, Brownsville Public Utilities Board
Overview
Brownsville Public Utilities Board (BPUB) manages critical electric, water, wastewater, and fiber optic infrastructure in South Texas.
BPUB serves the community by delivering essential utility services with accuracy, reliability, and efficiency. Ruben Cano, GIS Manager, leads a team that collects much of its field data in-house. His team locates transformers and poles, supports the right-of-way department with property corners and encroachment disputes, and collects elevation data for planning and water department projects.
The mission is clear: collect accurate field data, support utility operations, and help departments make better decisions with reliable location information.
The Challenge
Before adopting Bad Elf GNSS (Global Navigation Satellite Systems), BPUB relied on expensive legacy GPS equipment that no longer met the team's field needs. The older units created several problems including:
🔥 Legacy Equipment Failed in the Field
The previous handheld devices struggled in the intense South Texas heat. Screens became unresponsive. Field crews could not rely on the equipment when they needed it most. The equipment also lacked the versatility BPUB needed for modern GIS and utility workflows.
⏱️ Post-Processing Slowed the Team Down
The previous GNSS workflow required lengthy post-processing. Field crews collected data, uploaded it to a server, and relied on office staff or editors to manually process the data. That process added extra steps, extra office work, and extra time. It also limited real-time decision-making in the field.
The workflow depended on more than field collection. It required subscriptions, server uploads, manual review, and additional office processing before the data became useful.
❌ Support Did Not Meet the Need
BPUB needed better vendor support. The team needed more than equipment, they needed a responsive GNSS partner who understood field data collection, utility workflows, and the Esri ecosystem.
The Trigger for Change: Bad Elf
The trigger for change came when BPUB found Bad Elf GNSS solutions. BPUB needed high-accuracy GNSS hardware that could quickly and easily replace unreliable legacy units. The team needed a "bring your own device" aka BYOD-friendly solution that worked with modern mobile devices, field applications, and real-time workflows.
Ruben Cano and his team selected Bad Elf because the hardware met the need in the field and supported the direction of the organization. BPUB choose Bad Elf for several key reasons:
- Robust, Versatile Hardware
- Strong Value at a Lower Cost
- Open Ecosystem & Free App
- Responsive Customer Service
- Peripheral Device (Laser rangefinder) Integration
- Esri Ecosystem Integration
- Streamlined Procurement via TXDIR Contract
Operational Impact & ROI
Brownsville Public Utilities Board saw clear operational gains after moving to Bad Elf receivers. The biggest impact came from replacing slow post-processing workflows with real-time, Bluetooth-connected GNSS data collection.
| Category | Impact of Bad Elf Integration |
|---|---|
| Data Collection Workflow | BPUB shifted from manually office managed post-processing workflows, to real-time data collection through Bluetooth connected devices. Collect in the field. Ready when you get back to the office. |
| Hardware Durability | Bad Elf hardware (IP65 & IP67) worked reliably in South Texas heat. A Flex unit survived a fall from a tripod into a truck without damage or loss of accuracy. |
| Accuracy & Quality | BPUB achieved real-time, sub-centimeter accuracy for essential asset location via RTK corrections. The team used GNSS provided metadata to better prepare for future national datum changes. |
| Field Efficiency | New Bad Elf Flex firmware with "Instant Accuracy" and auto-start configurations made the system easier for field teams to use, especially for less frequent users. Less setup and clicking leads to less human error. |
| Rangefinder Accuracy | BPUB used the "laser rangefinder for offset workflow" and reported accurate results at distances greater than the recommended 100 feet. |
| Procurement | BPUB saved time and resources to purchase the equipment by using the Texas Department of Information Resources (TXDIR) contract as the purchasing mechanism. |
| Vendor Support | BPUB received more responsive, knowledgeable customer support from Bad Elf than it had with its previous vendor. Bad Elf provided fast integration support and deployment, aiding in "uptime." |
| Equipment Cost | BPUB acquired multiple Bad Elf Flex and Flex Mini units for the cost of traditional gear, saving Brownsville taxpayers thousands of dollars. |
Advice to Other Districts and Similar Organizations
Brownsville Public Utilities Board experience gives other utilities and public agencies a clear lesson: do not modernize field data collection by replacing old hardware with another closed, expensive, and rigid system. Choose a GNSS partner that supports the way your teams actually work, in real-time.
BPUB selected Bad Elf because it delivered high-accuracy GNSS data, worked with modern mobile devices, integrated with the Esri ecosystem, supported peripheral devices, and reduced the burden of post-processing. The team valued Bad Elf's durable hardware, open ecosystem, responsive support, and streamlined purchasing through the Texas Department of Information Resources contract.
For utilities, districts, and public agencies that need to modernize field data collection, Bad Elf offers a practical path forward. Bad Elf helps teams collect better data, reduce field friction, improve confidence, and move away from legacy workflows that slow everyone down.
